Incase anyone is confused, methadone and hydrocodone alone would NOT cause the smell or majority of serious symptoms, he was adding some type of aerosol combined with a noxious irritant and poison. The drugs were added to discredit the victims and confuse medical staff by making appear the victims were addicts and also giving drugs to their newborn. There's little doubt he would have continued these attacks until someone died and was wrongfully imprisoned, guy needs to have his charges increased.
Thank you. I was like this is so bizarre, how would those drugs cause these symptoms. Thank God the baby didn't touch any of the crap he was squirting in there. It definitely would have killed her.
*IN CASE
@@Flamsterette Wow! So helpful to let us all know about the simple but obvious typo.
thats a good point, however i dont think the opiates would enter the occupants body from liquid near the door. I think the purpose was knowing that the smell/liquid/residue may be discovered. its just enough to trigger a police testing kit, with how strict China is, he probably thought that when theyd go to the police, about an unknown substance, theyd test it, detect trace amounts of drugs and put them in jail, regardless of circumstances. Its just a cover for testing kits, that once the drug is detected theyd be in jail and looked down on, and no further testing would be conducted.
@@It-is-me...Melsie I refuse to enable bad spelling and grammar.
Imagine what kind of father and spouse he was to his own family. What a sadistic sociopath.
Some psychopaths can completely switch personalities from one family to another.
He's a psychopath, he's calculated
Technically he's attempting to improve the living standards for his own family, at the cost of another. If anything, it shows he's willing to expend more effort and risk, compared to others, so your comment isn't fair. It's the same as suggesting employing self defence methods suggests you attack your own family, which makes no sense.
@@Kelthor85maybe you’re coping with being similar to this guy😂 at no point does Grande state that the FAMILY had ill will towards the noise. He stated HE HIMSELF was woken up by noise. Psychopaths are selfish in nature u fk!!
@@blakewright3589 Apparently this psychopath preferred murder and/or jail to earplugs.
The fact he wasn't charged with attempted murder or at least aggravated assault of a minor is depressing and astonishing. He deserves jail time at the very least. I am so upset about this, I pray the poor family is okay. I hate this criminal.
He assaulted everyone living there, as well as any potential visitors, maintenance workers, etc.
Could also be considered terrorism
The victims are muslim, that‘s why they don‘t care.
Maybe he got some sort of plea. I'm discouraged too..
Murder is VERY serious and all angles have to be looked at before we use it to pin on someone. In my opinion this was not attempted murder. He was using irritants to make them move out and I think his intent was always to make them move out, not kill anyone. We have to look at the gravity of the crime here. A lot of neighbor disturbances end with someone shooting someone directly.
I was a biotech student myself, and had plenty of access to all kind of chemicals and noisy neighbours. Have had to move out because some of them made so much noice. I sometimes had to call the police, but never had I thought that to poison them was in any way acceptable
I have many thoughts:
- how did he get hold of the illegal substances?
- he should be blacklisted from chemistry programs for abusing his position in this way
- he should not have been able to be bailed out, AT LEAST before he himself had given the police a list of all the chemicals he used
- some of the chemicals can be cancer-causing of genotoxic, which in itself should be a major criminal offence, and may have been something the family he poisoned shpuld have received additional compensation for
- he shoule be locked up in either prison or a mental institution because of the seriousness of his actions
- I somehow feel this may not be the first time he has poisoned someone intentionally
Very well said 👏👏👏
Can you imagine how he's feeling now kicked out of chemistry school his career ?
I don't think it's his last time either.
Tick tock tick💣💥😳
use ear plugs
@@johnloza-ix5te Stupid comment. Earplugs don't work when someone turns on really loud bass, or is just literally partying right outside youe room. Some students have sleep problems (I wasn't even one of them), and those can't even tolerate half the noice. When it's legal to party, I let people party. If they are way over the top. Fuck them, I have myself to care about
You can order literally anything in relatively small quantities if it's for research purposes.
@@cee-emm We had a "radioactive waste" bucket in our physics lab... much easier to get something in university, and pretty sure a regular person wouldn't be able to order THAT. There was all lind of toxic stuff in pretty large amounts at uni. Plus, what really harmful substances can a regular person juatify with "research purposes"?
I can’t believe he was given bail. He is a danger to anyone in his path.
Yeah people getting locked up for chemicals yet he’s out smh
He's a psychopath.
It's a war crime to use chemicals but he gets bail. Lmfao
He sounds as if he's a Chinese citizen. Yank his visa and ship him home.
He knows how to weaponize dangerous substances and is suspected of attacking a child. And they let him out undr bail ? Really ?
If the baby’s hair was falling out and she was coughing and vomiting I believe one of the chemicals was poisonous. He wasn’t just trying to make them move. He was trying to make them sick or kill them.
It’s extremely upsetting that this man was released from jail. He’s a danger to society.
If he wanted to kill them he easily could have. He was trying to make them sick from an unknown source so they would move. The hydrocodone and the methadone were red herrings should they go to the doctor and get a tox report. When opiates show up on the first screen they're immediately discredited, and the pathologist will look no further.
I wonder if he’d been able to obtain a dose of Anthrax or such. Remember those Tokyo subway attacks.
@@A.Krispy He doesn't need to obtain anthrax, he could easily make it. If he wanted to kill them, he easily could have.
@@ElSantoLuchador Not to be that guy, but Anthrax is a bacterium. You can't make bacteria.
Oh, Hell Yeah!🤬!
Narcissistic / Controlling / Total Disregard For Other People. He needs to do about 5 to 7 years and encouraged to seek psychiatric treatment while imprisoned.😠.
Brand New Baby! WTF!🤷♂️🤦🤷♂️
If you have had a baby or child and had to helplessly witness them vomiting you know how horrifying this must have been for these parents. To see a child gasping for air, stomach convulsing, eyes watering and them choking gives parents a helpless and sad feeling. I hope they give him minimum 20 years.
We had a downstairs neighbor who would always complain, to the building admin, to us about noise. They just had a baby and said that our noise was keeping the baby up. One time he came banging on our door arouns 9pm, and yelled at us to tell our kids to stop running around. The funny thing is, we don't have kids in the apartment. We were just three female teachers. At that time my two roomates were out, and I was working online. So it was pretty quiet. He was so furious, came in uninvited and looked for the kids. I told him, there were no kids, and he saw I was working on the computer on the dining table. So obviously I was not running around too. He looked perplexed. I even opened all the rooms to let him see that there were no children. I complained to the admin, I told them that we have videos we can show that there are no kids at the alleged times. I told him next time I will be calling the police. They stopped complaining. They moved out after a few months.
Some people don’t know how good they have it with quiet, considerate neighbors who have positions of responsibility that require them to be very stable and go to sleep early.
... Ghosts 👻
Maybe rats in the walls? Here in AZ the pack rats sound like a bunch of people running around when just one gets into the attic!
i need to know whyyy he thought there were kids
The same thing happened to my mother. She was in her 70s at the time and dealing with some serious health issues. Occasionally two of her grandkids would come and stay with her on the week-end. Her downstairs neighbour complained relentlessly about the noise - both to her and the strata council. My mom never, ever let the kids run around the apartment. They finally realized what a liar he was when he presented a list of dates the kids were supposedly noisy - and they hadn't even been at my mom's place on those dates!!
Dude needs multiple charges of attempted murder
Really though, yes. I agree.
I wonder if he's ever done this before.
The so called American justice system do not want to upset China 🇨🇳 the man will go back to his home land unchecked and unchallenged.
I'm very surprised that his charges did not include child endangerment and attempted murder. Not knowing what the third substance is doesn't rule out how toxic it appeared to be. Some people have misplaced aggression and since this family did everything in their power to please him, they may have appeared to be a safe target for his frustrations and aggressions. Just my analysis.
Should have been attempted murder.
I would have given this sociopath a bottle of earplugs.
I wondering if more charges are coming, they arrested him with the first set to get him off the streets, but because the case is so strange they are looking into what else to charge him with.
What evidence gives anyone the impression that it was attempted murder? I don’t mind people speculating such things - for sport, but it seems like you all are implying that it’s obvious what his intentions were, as though there’s little room for any other possibility. I can think of a dozen intentions that don’t involve death. Yes a possible outcome could be death, and yes it’s possible that he didn’t care if his actions could/would lead to their death…but then that becomes an involuntary/reckless homicide/manslaughter charge - not murder, not intentional. Besides, he added a noxious element to the mix - which contradicts any intentions of killing someone over time. A murderer, using chemicals, that takes weeks/months to be effective, would not complete their task if the victims were always aware of the source and presence of the poisoning.
He should be charged with three counts of attempted murder if the unknown ingredient ends up being a toxic poison that would have killed the entire family if he hadn’t been caught.
I lived in an apartment below a couple with a baby, and I assure you there is a lot of noise that carries through those floors, and it only becomes worse when they become older. Toddlers literally sound like elephants when they walk. As someone who needs complete quiet in order sleep. I sometimes felt on the verge of insanity because of the sleep deprivation, whereas the other people I lived with were heavy sleepers and weren't bothered at all.I learned from that experience that I always have to live on the top floor of a building or in a detached house.
I always get a top floor end unit, with the bedroom on an outside wall. I won’t waste my time looking at anything else.
Or get earplugs?
When I had an apartment, I slept with ear plugs and put noise canceling headphones that played white noise over them. I’m a very light sleeper unfortunately.
White noise may help. I usually sleep with the TV on. That’s made me less sensitive to noise over time when I’m sleeping.
In Italy there was an incredibly famous case some years ago, known as the Erba massacre. A couple complained for months of the noise a family downstairs was allegedly making, and they were obsessed to the point they complained of noise even when the family was out of the house or sleeping. They called the police so many times on the neighbors that *they* were told to stop or they would be charged. They ended up murdering the entire family downstairs in a horrific bloodbath. Both perpetrators had very low IQ and lived an incredibly isolated life, only interacting with each other.
Just as cold bloodedly as he poisoned his neighbors he ruined his own life. I'm speculating that Li is a giant nutcase.
I dunno. He looked like he wasn't tall. Maybe he was a short nutcase?
Why was he not charged with attempted murder, assault, bodily harm, etc.? 😒
Good question. That is definitely first degree assault and more.
I only hope that they are reserving those charges for when they have obtained even more evidence and delaying charging him with these somehow enables prosecutors to ensure he cannot possibly escape punishment for those crimes.
@@Liliarthan an update for you: he was deported back to China. Awesome!
@@operandexpanse wow, thank you! That’s good news.
Acoustics in apartment buildings are weird. I remember an apartment friends owned 3 floors up and the long running battle with downstairs neighbours complaining repeatedly about the noises and furniture supposedly being moved. My friends were were not noisy people yet they bought carpets and rugs doing everything they could think of to resolve this issue and get some reconciliation. In the end nothing seemed to appease the neighbors and they made formal complaints to the building board and there was mediation. The crunch came when the neighbours continued to complain about the noise. The thing was that my friends were away for weeks on holiday when this was supposedly happening and the apartment was empty! They could prove this. That was finally the end of the battle, because it demonstrated evidentially they were not making whatever the percieved noises were. In the meantime it was a very stressful situation for them. All that said this perpetrator is deranged.
How is this dangerous psychopath not in prison? 😱🤯
I didn’t know he had his own children! How could he be so unempathetic towards the baby?
You have to realize alot of people that practice breeding practice THIER culture, on this land, with our rules.are you truly stupid or just bored?

@@livinthehighlife93stupidest comment I've seen all year
@@livinthehighlife93 Racist.
@@livinthehighlife93 What???!!! I'm not Asian, but that statement is untrue and dangerous.
I'm getting the idea that he was prejudiced against the family. He just plain didn't want them there. It's awful that he felt it was smart to use chemical warfare against this family. Sick man.
Clearly it wasn't any perceived noise...he could have just slept with earplugs in. As I do. Due to noisy neighbors, and in the past, roommates.
I know it's not fair to paint him with a brush because of where he's from but Chinese are extremely racist, generally speaking.
He probably was angry that he didn't get into medical school and had to get the Ph.D. in chemistry to satisfy the expectations of his parents/family.
Well he bought the girl a dress...and asked the dad how she was doing ? He just sounds like a crazy bastard
@@Aaron-kj8dvamericans are extremely racists, 2020 and george floyd protest showed that
This is crazy that he was released to go same home where the victim is living upstairs. Think how terrified it was for the victim family. What a beautiful law we have. Sometimes I feel like we have laws to protect criminals only.
This was so disgusting.
Wasn't even that much coverage on the news.
They call them the moral society?
These kinds of people are the scariest amongst us.
I hope that family is okay.
He needs to be prosecuted.
This was attempted murder.
Thank you for posting.
Whoa, I had no idea he had kids of his own, and that he had initially been friendly. That makes this so much worse IMO. It sounds like the poor family did everything they could to accommodate Li. Wow.
who knows , i have had noisy neighbors and they had straight up lied to the landlord about trying to be quieter. i’m not saying what he did with chemicals is right but i don’t trust the family’s side 100% either.

I live in an apartment with a neighbor like this, she absolutely hated I had two young children and would complain constantly. She eventually set my balcony on fire, well tried to it backfired (literally) and set her own on fire. Needless to say she was evicted. People like this exist.scary
Wow I’m so sorry she’s sleazily jealous and straight demonic ! Happy she’s gone x
Dude was complaining about a creaking toilet seat in an apartment above......dude was out of his mind.....smh
Evil incarnate. Watching him sneak up, do the deed and walk away in a slower, upright triumph in clear satisfaction is chilling.
He did not walk away in a triumphant or satisfied way, he just walked away quickly incase they came out. He is trying to not get caught so his body language is exactly as it would be predicted.
Very likely he was flipping out because of the pressures of completing his PhD, future uncertainty, etc. He was using the lab at the university to synthesize a compound like sarin gas or equivalent which at very low doses simply makes people sick. The methadone and hydrocodone would be carried along with it and yield false positives for opiods, which would divert attention of medical professionals from the other effects being reported. Hair and skin samples would suggest long term opiod use affecting their child, which would get them into serious trouble, even have the child removed from their home by authorities.
This guy is seriously unbalanced and became evil.
Sarin is a great thought, but it's odorless. It's scary that we have to worry about more than convicted sex offenders in our neighborhoods.
This guy is for sure a psychopath and will do something like this again.
If I was that family I would be so scared he would retaliate for getting him in trouble, as they should have, he deserved it. Seems like a narcissist psychopath and people like that don’t change.
I pray the family doesn’t have lasting health problems, especially the little innocent baby. Sick anyone would ever knowingly hurt a baby.
@@HeatherHolt Agree that he is probably on the ASPD spectrum. Btw, all psychopaths/people on the ASPD spectrum are narcissistic. Hence it is a bit redundant putting them together--sort of like saying ATM machine.

@@trialgoddessShould we have a biohazard chemical offender registry?
This is like my Borderline mother, claiming someone flushing a toilet, several floors away at the opposite end of the building, would wake her up and expecting everyone to tippy toe around her (figuratively and literally). She would fixate on a person she initially said was "a great neighbour", then she'd flip and they could no right. She'd then decide they had it in for her and every small noise was purposeful on their part and some sort of slight against her. This guy took it to a whole other level. He wasn't charged with enough imo, he needs a grievous bodily harm charge also at least.
Yikes, I am sorry you had that as a mother. Sounds horrible. I hope you have recovered.
Sounds like mine, too. She was a very light sleeper
This guy is absolutely horrible. It’s frightening bc we all live somewhere with neighbors! I wonder if more charges will be added, like child abuse / endangerment of a child. My heart breaks for that newborn inhaling those toxic chemicals.
Can't sleep until I've seen Dr Grandes latest video.
This reminds me of a story from maybe around the 70's where a retired chemistry professor used Thallium to poison his neighbors due to excessive noise or so he said. He broke into their house when they were out and put it glass coca cola bottles and was even able to put the caps back on so well it wasn't noticed as being tampered with. Members of the family who got sick were in the hospital and the doctors could not figure out what was happening and they had very serious symptoms. The mother of the family died and one of her sons was severely debilitated afterwards. I'm pretty sure another son and a daughter experienced much subtler symptoms but non the less they were poisoned by this psycho. Due to a lack of evidence a police woman had to go undercover to befriend him in order to elicit a confession or have access to his home to look for evidence and that's how he was nailed. Dr. Grande you always mention narcissist behavior, arrogance, grandiose behavior and when a person is very intelligent how conniving they can be and this guy was all of that. It was a great read
Yeah, these were members of Mensa, right? This story was excellently covered by Mr.Ballen.
If you enjoy "mr.ballen" you probably enjoy having an LP player playing the sound of nails on a chalkboard when you're going to sleep.
I remember this from Unsolved Mysteries... or Forensic Files, one of those. That was an interesting story.
He didn't poison them just because of loud music. The entire family were loud, obnoxious, and disrespectful. The couple owned their house and had lived there forever. It was a quiet neighborhood until this new family moved in. "Neighbor problems" get very violent, pretty fast. Watch "Fear thy neighbor". Once one person feels disrespected, they usually do shit back and forth until it ends badly for everyone.
Anyway, I don't feel bad for the family in that case with the Coke. They were horrible. All they had to do was be decent Neighbors.
In this case, the Chinese guy was a complete POS psychopath.
I hate loud, obnoxious neighbors. I refuse to live in an apartment around a lot of people. Apartments are not built well, to keep people happy. They are thrown together to make a lot of money and too often you can hear too much. In this case though.....if these people did all these things to try and keep the peace, and be quiet, then he is most definitely the assh*le. This really seems like a "no bail" situation. He is absolutely a danger to anyone that annoys him. He shouldn't live in an apartment then. Or move to the top floor so no one is above him. He has 2 kids, I bet he doesn't give a shit that his family is probably really loud to his downstairs neighbors.
It is really weird that he waited to fill the syringe until he was by the door. Wouldn't you fill it in the house, then just bring the syringe with you? It was like a movie, the villian loading up a syringe where anyone could see him. I hope the victim family is doing well and has no long term problems. I hope this POS goes to prison.
@@elijahjakobsen7898 Well, we all have our opinions, right? I think he’s an excellent storyteller, who’s gotten so much better as time goes by.
Disgusting behaviour and an insane individual. He should be charged with attempted murder.
Having worked in housing I think he could hear acceptable everyday living noises but to him it was unacceptable. Some people are crazy, one woman complained about the short jingle of the ice cream van/truck and expected me to do something about it 😂. Fingers crossed the family will suffer no long term side effects. What an insane neighbour.
I was watching a true crime video today about a 1988 poisoning case where an entire family was sick and a neighbor was putting an old type of rat poison in the families Coke. Made their hair fall out. The guy who did it was mad about loud music.
Yea that was on forensic files too, him and his wife were involved in murder mystery games, i think the wife was involved in that case. They both had very high IQs and were considered geniuses
@@allday-xx4zwdid the victims test positive for opiates? Im not sure how it would get in their system
Sounds like thallium.
@@allday-xx4zwif he aerosolized the mixture, it would’ve been airborne & easily inhaled as evidenced by the baby coughing, the bad smell & irritated eyes. Whatever it was got absorbed through mucus membranes in the nose, eyes & mouth & also inhaled.
Did that 1988 case involve strychnine? I think that was common in poisons back then.
If the building construction is so crappy you can hear neighbors on the toilet move to a new place if you can’t afford it cope but this is insane

@@Flamsterette Get a life
That’s how even “luxury” places are built now.
Many people with Autism, PTSD and anxiety/depression are very noise sensitive.
Be aware of the noise that you make and endeavour to be a good neighbour.
No
My first apartment was excellent: great location near my university, more space than I needed for a relatively low price, and nice neighbors. Even the property manager was pretty responsive. The only problem was my upstairs neighbors. They were a middle-aged couple who probably weighed around 500-600 lbs combined and whose apartment had a metal spiral staircase up to a loft. The husband was a concert pianist and had a baby grand piano in their apartment; naturally, he would practice all day long, which wasn't the worst thing in the world--the guy was a professional pianist, after all--but between the piano, the couple going up and down those metal stairs, and just the noises of two overweight people on different schedules moving around an apartment, there was rarely a moment when some noise wasn't coming from above. I'd even hear them get out of bed in the middle of the night and stomp their way to the bathroom. But I never said anything to them because I was sure they weren't doing anything malicious--I never heard them yelling, never heard a TV or stereo turned up too loud, never heard them up late making a racket wirh friends. In other words, they never did any of the inconsiderate things people often do in apartments. They were just big folks walking around and playing piano in an indifferently constructed building with a floor/ceiling that was probably as thin and flimsy as the law allowed it to be. All things considered it could have been a lot worse, and since they never complained about my music or the occasional noisy late night drinking session with friends, I didn't complain about the thumps, bumps, and piano concertos constantly emanating from overhead. Apartment living means picking your battles and learning to tolerate the sounds of other humans. Within reason. That sure was a great apartment though. Damn thing even had a balcony and a huge walk-in storage closet. And not one but two reserved covered parking spaces. Something like that in the city today probably costs ten times what I was paying for it.
you sound awesome! As someone with a musician husband, thank you!! We got lots of complaints constantly 😅
My apartment is very badly constructed and I struggled for a year and a half with noisy neighbor below who only recently moved. I had a lot of hassles and a lot of nights with little to no sleep and spoke to the landlord quite a few times, and even saw a doctor and therapist about sleep, but it never ever occurred to me to poison her.
No shit
Construction makes a huge difference! I very rarely hear my neighbours and I'm in a 6th floor apartment.
Well id hope not
Just buy a house
And what happened when the next neighbour moved in? Let me guess, it was noisy again?
I had a roommate once that would get so upset over every little noise from the upstairs neighbors. She seemed to take it extremely personally and once she was aware of the noise, it became an obsession where she was convinced they were doing it on purpose to annoy her, even though they had never met. The way she stressed out stressed me out, so I had to get the heck out of there. Glad I did because she was a nutcase.
Every sound is a noise directed against them they think
maybe she was autistic with extreme sensory issues. help and support would be better than judgement.
@@abody499 they are judgmental about sound emitters other people
Or should I say other sound emitters
Some people are just hypersensitive to noise. My brother-in-law constantly wore a pair of old headphones when my niece & nephew were kids to block out their noise. I see it as just another 'thing', like hypersensitivity to light or allergies to certain drugs ... just different brain wiring &/or chemistry. Though I don't know what was going on with this dude in the video.
Hearing all that noise tells me the apartment was constructed with poor materials for the floors.
Some years ago, I had a similar case with my neighbour below, who complained that I was walking loudly during the daytime (!). One time he came up to me and threatened to beat me up as soon as he woukd no longer be under parole. I had to call the police. Fortunately, he moved out after a few months. Such people are dangerous.
I'm glad he was arrested before he got his doctorate.
I had a neighbor complain about me like this guy complained. My neighbor used to scream at her ceiling/our floor whenever we walked across the floor, I mean, like a crazy person. She'd wake up at 4 am and start slamming her bedroom closet door to wake us. She put screws under the tires of my car to puncture them. She spread rumors among other tenants about my spouse. Multi-unit housing anywhere can be sketch, but low(er) income ones often seem to be dens of sickness and dysfunction. My dumb idea of saving money by living in such places was NEVER worth it!
I lived above this retiree about thirty years ago. It was a three floor building owned by a doctor who had a surgery in the front. Nice property with a courtyard that backed onto an art museum. I think the old guy got cheap rent for doing caretaking stuff. I think this made him believe he had some kind of jurisdiction over the property and he would scream and carry on about percieved noise. He would put a radio on full volume and hold it to the ceiling. Eventually I had it with his harassment and decided to move. I had a garage sale in the courtyard to get rid of stuff and he came out and kicked everything violently and screamed in front of people. He was out of his mind. Well the old f*** will be dead now but a lot of neighbors are loose units and a danger from my experience.
Omg. This is terrible.
I had this exact same situation in the post happen to me. Well I don't know what was the substance but it was this yellowish sticky goo in tiny blotches all around the house. It started happening when I lost a set of keys and didn't change the locks.
I still don't know who or why, but a few times when I had been away for a day or two, I'd come home and be hit in the face with this super pungent chemical smell. It burned in the throat and made my skin beet red, and I would lose consciousness. The smell came from these yellowish gunk splotches that were both visible and hidden all over my apartment, they would fume worse if it was a hot day. When they had given all of their fumes, the blotches would dry out leaving this white powdery substance and burned marks on some surfaces. It was a hell to get rid of it and after the first time I didn't contact anyone but after the second time my landlord gave me an another apartment started investigating it. If I would be losing consciousness because of the fumes, it would ease as soon as I laid on the floor since the gases wouldn't stay there. Also my skin would stay red for days and I could like taste the stuff oozing through my skin and to through my tongue in my mouth, it was pure hell!!! Still don't know what it was, I was hoping someone could take an educated guess??
Had an old person always micromanaging us. We weren't loud and always considerate of our neighbors. My home is a place of quiet and comfort. But my neighbor would say he hates it when we turn on the bathroom vent. He can't stand that noise. Well everyone has a automatic bathroom vent when turned on. I dont get it.
I remember how all of my neighbors were loud and obnoxious, all the damned minutes of the day. Then, my doctor prescribed a better treatment and suddenly they were... still noisy jerks.
At this point, I no longer cared about their behavior because mine was being treated. It was, and is, a wild ride
This story made me recall an interview I watched a few years ago with a Chinese activist who had fled China and at that time was living under an assumed name in fear for her life. She said that the repressive nature of the ruling party has created a nation of psychopaths…cruel, sneaky, paranoid, without empathy, dishonest, etc., and that these traits have literally been bred into subsequent generations as good, honest, caring people are systematically eliminated. I know little about the Chinese people, but this interview came to mind as I listened to the behavior of this man.
Asian men are more dangerous than we thought. They aren't confrontational, they prefer underhanded sneak attacks like chemicals. They are not a model minority, China has the right idea to keep them in check - look at how entitled incels are today. Thank God, Asian women have come to their senses and refuse to breed with them
The guy probably has a history of unexplained deaths in his circle of family and friends. Anyone check that out or do I have to do everything?

Yeah. Hard to believe he made it to the age of 36 without wigging out on anyone, only to try and murder a baby and her parents. Seems more like the crazy stunt someone would "Graduate" to rather than an Entry Level psycho move.
@@thatisabsolutelykooooge2211😂😂
What a bizarre behavior. It’s amazing how intelligence and wisdom can, at times, be so far apart.
Thank you, Dr. Grande. I hope you have an enjoyable LDW.❤️
at times? I think often. I have my own theories as to why, but I'm not sure I buy the myth of really any genius criminal.
you don't work with Asians much? I have lots weird of stories. Like my college professor who said his Chinese professor tried to deny him his doctorate because he was Indian.
"wisdom??" I'm not sure what that has to do with anything here. This guy is probably delusional, psychotic, and suffering from multiple personality disorders.
Would this be considered a war crime under the Geneva convention ?
@@pashon4percushonokay so it’s not just me, because I have some crazy stories too.
Any charge short of attempted murder isn't what this man deserves.
He's a danger to society.
I had noisy upstairs neighbors like this once. They got up early and made a bunch of noise.
I complained and they didn’t seem to care.
So I just waited till 10pm when they went to sleep and banged a broomstick on my ceiling. A little taste of their own medicine.
Way more effective than attempted murder.
My neighbor hates my other neighbors dog, he used to regularly poison the hallway. One time he removed the baseboard from his apartment, cut himself, and bled all over the hallway. He would scream phrases over and over again all night. He has been quiet since getting his eviction paperwork, but he is definitely disconnected from reality. That pup was one of the best behaved dogs I've ever lived next to.
Oh god, the poor dog. I hope it's okay.
I have no time for people who hate animals.
Yeah, stay away from apartments if you can. Poor neighbor and dog.
Wow wtf
My neighbour has a poodle cross. Cute as can be but it's bark is so shrill it travels through my entire house and it has woken me up every single day since they moved in over a year ago. I have spoken to them about it and keep the dog quiet but it only takes 1 or 2 barks and I'm awake already. As a shift worker I haven't slept more than 5 hours a night. The saddest part is I moved into my dream home loved it for 6 months now I have dark thoughts about that dog and I'm a dog lover by nature. There a 2 sides to every story
@@dougrogan379 Cruelly poisoning a dog makes for only one side. There is no excuse.
He was torturing that family. They went through hell, and that gave pleasure to the sadist.
Believe me, I've had some rude, LOUD neighbors, but I would never try to get them high and then sick simultaneously.
Noise travels in weird ways in apartments. I hear noise to the right of me and I’m an end unit. There’s thing to the right. Sometimes I hear marbles or chairs being dragged and the apartment next to me is Empty.
This guy was way too stressed....he flipped out bcuz he allowed it to become far too important, above his life, his family, his education and future.
Yeah, maybe he focused all his stress on the neighbour (& he was going through the most sressful time of his degree). I'm surprised he was complaining about footsteps & not the crying baby.
His own family probably created noise for the neighbors, too.
In this case, being too stressed is no excuse for his intentional harmful actions.
@@vicksenful My neighbors had a baby. I never heard it cry, but they woke me up at 2 am every single day. I think they were slamming the drawer of a changing table I imagine was on the other side of my bedroom wall.
The depths of the human psyche never ceases to amaze. Thank you for your informative content, Dr. Grande.
I... genuinely feel like he's either planned an attack like this for a huge part of his life, or previously attempted to poison someone in the past.
He has an air of confidence that really unnerves me
Noisy neighbours can be very frustrating & affect you mentally, believe me I know. People don’t seem to have off buttons these days & no consideration, & if you need get some sleep to get up early & go to work it’s very frustrating. But you don’t start trying to poison people, if you can’t reason with the noisy neighbours you have to try & move.
Gotta watch out for psychos in our community. Thanks for your video Dr Grande.
I'm so glad the act was captured on video and then taken to the police. Who knows what was going on in Xuming LI's mind, but whatever it was, we know that he is a very very bad man. At least he was kicked out of that university and is no longer allowed to live next door to the little baby he harmed. It seems like he should have been incarcerated for a long time too, or sent back to wherever he was from if he didn't have his US citizenship. Just think, he could still get his doctorate somewhere else and who knows what kind of crimes he might commit in the future.
I have similar experience with noisy upward neighbours but better communications have solved my issues and not poisoning your neighbours.
It’s scary to think he’s just even more pissed off now after getting in trouble and kicked out of school - who knows what people like that are capable of. Lack of empathy is the scariest quality in a person.
He should be deported immediately
Remotely inhaled (prescription strength) methadone & hydrocodone isn’t going to do much, particularly just “injected under a front door”. I’m fascinated to know what the other chemical was.
Thank you for speaking on this....this man is a very dangerous man to try poisoning an entire family and baby. Now he MUST GET PRISON TIME for this and let us see how he is going to deal with ALL of that noise. Loud spade games with the slapping of cards, loud ppl cussing and yelling, loud pots and pans banging around when prisoners cook, TVs are loud, loud music, loud recreational time with the weights, and last but not least LOUD SPEAKER SYSTEMS used by correctional officer day and night😭😭😭
If you can hear a toilet seat from another apartment then either you have sonic hearing or the floors are paper thin. That man was dramatic.
That guy is a psychopath.
Yes! Who is intentionally noisy and slamming things around a toddler everyone wants to sleep …
That poor family was much more patient with that psycho's unreasonable demands than I would have been. I am a very good neighbour but if I had someone like that near me I'd at first make an effort as they were, but then I'd be telling him to eff off.
Yes, I wonder did he try any noise cancelling measures for himself, or just complain? Ear plugs, white noise, etc. or just straight to poisoning his neighbors??
Especially from the sounds of it (no pun intended) it didn’t even seem like they were even making much noise to start with? Note it’s never stated the wife complained to them about the noise. But guys clearly crazy , she probably can’t do anything 💀
Dr Grande has some sophisticated humor. Causes me to laugh in a sophisticated way.
i have had a neighbor that was making noise at 5-6am and 11-12 at night constantly for a year. there’s something about the disturbance that starting pissing me off over time, the stress and anger it like chips away at you over that time. he lied to the landlord about trying to be quieter also. i’m not saying what he did here with chemicals is right but i totally get the anger side of things.
Modern affordable apartments are shoddily built, with no sound proofing between floors - so unless the residents are awake & sleeping on the same schedule, expect aggravation. Of course, non-criminals don't try to kill people who annoy them.
My husband and I lived in a small apartment while we attended law school. We thought the next door neighbor's large cat had unusual "meowing" sounds until we realized she (neighbor) made the sounds while in the throes of passion with the boyfriend du jour (or du/de nuit?).
Good point about the cheap, shoddy construction. I lived in a new building, and could hear the neighbors’ cabinets slamming. They were not slamming them, but the design of the cabinets and the building construction were so bad you needed to deliberately keep hold of the cabinet handles and close the doors quietly in order not to make a lot of noise.
Wrong and wrong. This is America. Not that shithole country you fled. All building projects must meet the same building codes. You're going to hear noise in an apartment just like you would in another part of your house. If you don't like hearing other people's noise. Get a private home or build a cabin in the woods.
I dunno mate, guy was a phd student. Probably wasn't a criminal up until that point
The odd thing is I know darn well Chinese people in their cramped high rise apartments in China suffer far more noise than anything this guy was hearing from his neighbors in Tampa, you’d think he’d be used to it.
I thought the same. Even walking in the streets they are packed in like sardines.
Yeah same thoughts here
Super racist comment.
My thought exactly. He was just looking for a reason to harm this family. Was his thesis about poisoning maybe. They were his case study.
@@pjnix5618 lol "Super racist" How??
Respect to Umar for waiting to get a better angle. How many people would have tried to confront him with the bad angle footage, just so he could deny it and the police could say it wasn’t enough evidence to charge him. I know I wouldn’t have had so much patience.
Vindictiveness is a common narcissistic trait. He was probably jealous about something. He should have also been charged with assault and attempted murder.
I doubt that he will find prison to be a quiet place. (Assuming he is convicted.)
I once lived on ground floor of an old house with hardwood floors, every footstep, chair scraping seemed loud especially at night. I moved.
Neighbors can be very disrespectful towards their own neighbors. I have the same problem coming from the downstairs and next door ones. The downstairs makes so much noise after 11:30 pm that wakes me up scared. The next door one used to talk so loud till 3-4 am at his balcony that is next to my bed room window which kept me awake at night. The problem has been partially solved besides the downstairs guy. It’s tough to live surrounded by unconsidered people. I wish I could live in a house without anyone around me for miles and miles.
Dr Grande, Some ppl are very sensitive to noise, and they hear things very intense, I don't agree with the way the neighbors criminal behavior, but I also understand how he may have felt.. I'm just happy that nobody was hurt, this could have been so much worse,
The most shocking aspect of the case? That this monster of monsters is not on death row, that it is free to continue to terrorize the public.
I gate to say it but i hope he slips up and does it again so they would put him in jail or out of the country...
I went in feeling some sympathy for downstairs neighbors because I have had some terrible ones, usually partying college students who decided to live in housing nowhere near the university and still thought it was ok to hoot and yell and listen to loud dance music at 1am. But it doesn’t sound like they were nightmare neighbors at all. But even if they were, poisoning them is NOT the way to handle it! Such a scary situation for the upstairs neighbors.
I also thought that it was going to be a story where he lost his mind as a result of repeated sleep deprivation with a new baby above and believing that the upstairs neighbours were completely inconsiderate (and I've also gotten really angry about neighbour noise repeatedly at 3am that I thought they should have known better) so I was shocked to hear that they had even tried to address the noise complaints in this case. But in his mind, he still believed the neighbour was making the noises, I bet. Maybe some paranoid delusions. Of course, that doesn't make it any better. But I don't know if he just spontaneously decided to attack a family for no reason - I'm guessing what he was complaining about felt real in his head.
Yes, I'm not excusing his criminal behavior but I've had some awful neighbors too. One would blast his music at 4a during weekdays. I called the police on him a few times and with management until they kicked him out and recently I had an issue with a neighbor smoking pot. The smoke and stink would permeate to my whole unit. I read my contract and called management several times until they sent an email to cease and desist. So far so good. I've been able to breathe fresh air in my unit again. Still, I would never try to do anything criminal against anybody. The extreme thing I thought about doing was to move out but it's scary to move out too with rents being so high everywhere.
I couldn't agree more with you.
I had a neighbor who was really mentally ill. One of his many problems was that every little sound which came from my apartment was driving him mad.
It's very disturbing he was released from jail clearly he is a threat and there needs to be an investigation as to how he got those chemicals and he should be kept in jail till he tells investigators what the unkown chemicals are and if he has done this before.
I gotta say, great work on the dad's part. I have no clue how long it would take me to figure out it was someone poisoning me through the front door.
Yup it was a really good idea he callee the fire department's hazmat team
I guarantee you, I would’ve died before figuring it out
xuming li probably has a history of this kind of behavior that could become known if this story reaches the places he has been?
How evil is he to poison a newborn baby because of noises? They could not help it and they bought rugs and soft slippers to make it better. It’s incredible
If anyone ever belonged in jail for a few decades it's this guy.
That is absolutely horrifying.
We may have more clues to Xuming's personality by his upbringing. Just my opinion but this type of vindictive behaviour is probably not the first time that it has happened.
Asuming he even was vindictive, its not clear what his motivation was.
@@clmBerserkermotive or no motive, it still does not justify poisioning a neighbor. Poisioning a human or an animal for that matter is unacceptable in my books no matter the circumstances.
I agree. The whole plan was too well thought out for it to have just hatched. There were likely other times and this is just the first time he was caught! Cheers to the husband for setting up that camera.
@@pennyc7064
I never said it was justified just that his motivation dosent have to be some form of revenge, could be some controll thing or something else. It dident sound like the family did anything to provoke him, even sounded like they went out of their way to try to appease him.
@@clmBerserker You're joking. Right?
A chemist who poisons children and uses his skill to destroy his enemies? Where have I seen that before?
Seems like it would be easier to just move to the top floor, but this dude chose to try and poison a family that has a little baby. What a strange and evil man.
It's unfortunate when you're too poor to live in your own house, you'll always be stuck under someone in an apartment.
Some people who never lived in an apartmentbilding before but grew up in a one family home get stressed when they hear noises around them from other apartments. No solution but to get used to it or move
This guy will do time if there is any justice. I pity his family, but the real victims here are evident. I hope that this family suffers no long lasting effects from their continuous poisoning.
This may have helped his family. I sure he is hard to live with. Controlling demanding his selfish rules. Maybe if true his wife will have the strength to move on to a better life for herself and children??
Prison, then deported straight back to China.
He was just one of these people who is permanently being bothered by everything. Extremely dangerous individual.
HE IS FREE NOW ON THE BAIL. CONGRATULATION!!!
He brings great disgrace to his family and community, and lost all face.
The refrigerant used in air conditioners, HFA, is also the propellant used in nebulizers for inhaled medications (as for asthmatics).
It's likely the chemical was an aromatic compound, which are also carcinogens.
It's not his family's or his community's fault, I don't see why they should be disgraced.
One word.. Chinese!!
@@sheilagravely5621 Most Chinese people are decent, some are good and some are bad. Just like people of every ethnicity.
It's the CCP that is horrible, just like Leftists in this country.
Are you saying ac and inhalers are carcinogenic? I'll Google.
I would move rather than going to prison and have my life/future destroyed. Clearly a bully.
When I was a dumb, naive college student living in a crappy apartment, sandwiched in between the first and third floors ,the upstairs noise drove me crazy. I was convinced that the girl upstairs was using a mini-trampoline late at night or early in the morning, especially on weekends. I must have had a pure mind back then
How in the world was he released! I believe that this has the potential to become a case of attempted murder.
It's very noisy in jail and they leave the lights on at night, lol.
Such a strange man, that poor family with their baby girl! Thank you Dr. Grande for another fascinating video!
I knew this had to do with the victims being very bad neighborns
@@lilsyevasifuentes7628 Did you not listen? They weren't bad neighbours at all. In fact they showed more patience than most would have, and appeared to go to a lot of effort to appease the pscyho.
As someone who is very noise-sensitive I can appreciate how insidious unwanted sounds can be... sometimes it can take a while to pinpoint exactly where it's coming from, and it's not always where you think. Sound will travel through pipes & duct work, down through floor ioists & common walls... and once you've become sensitive to it, any noise can chip away at your mental state & wind up even the most otherwise rational, calm person.
That said, the fact that this guy went from buying their child presents to lodging noise complaints & poisoning them within such a short time span suggests that he has far more troubling issues than noise sensitivity. Drug use could also explain hypersensitivity & hallucinations, possibly exacerbating a mental condition. And while he could be reacting to a prescribed medication, perbaps he got the methadone, etc through a dealer he already uses.
Regardless, I'm shocked they let this guy out without identifying exactly what he'd exposed the family & emergency services to.
I find it strange that Dr. Grande did not mention misophonia in his analysis/as a possible explanation. Misophonia is a well documented neurological disorder that causes the brain to hyper-react--typically with extreme anger and distress--to sounds that do not significantly bother most others.
Strange that the criminal initially was kind about the new infant - seemingly to offset his later intention to poison his neighbors, especially the most sensitive one - the child.
It’s always the “nice” ones
Premeditated. He wished to be perceived as a gracious and generous person. Then the other stuff happened.
I don’t think so. He probably got irritated, and more and more sleep deprived and angry, when the initial noise of having a new baby in the household didn’t settle down.
Imagine if Xuming had a toddler for a neighbor or a 6 year old that decided to jump on the bed. He complained of movement, not baby cries. Crying babies are loud, but crawling babies aren't. It would be impossible to please him.
Higher functioning people on the ASPD spectrum will often pretend to be kind, giving, caring, or the like to give a good first impression and to manipulate your perception of them. It is 99.9% of the time an act, not genuine/sincere.
While I abhor all crimes against our fellow man, there's something particularly loathsome and cowardly about poisoning that I truly detest.
And how most enjoy watching the victims cry out for help and go in circles trying to figure out the truth…. Like how could you not be anxious every night in bed? Monster is the only word I can think of.
He shouldn't be in America.
If you're having problems sleeping because of noise of a neighbor...they make these amazing things called "earplugs". And if you want to get real fancy and high tech, you can combine these with over the ear noise canceling headphones--though, kind of a hard to sleep with unless you're a back sleeper. But for most people and most situations, earplugs alone greatly help. As someone who is a light sleeper and has a partner who snores loudly sometimes, they are a godsend.
I have had noisy neighbours so noisy that neither earplugs not noise canceling headphones really worked. Some people are really loud. There can also be issues with vibrations (loud techno or hard kicks on the wall).
Other people in the exact same neighboring flats have been so quiet that I almost never heard them.
For the most part, Umar handled things very well. First, he tried his best to accommodate Xuming in order try to be polite and keep good relations with his neighbour. He also alerted everyone he should about the terrible smell and symptoms. It was so smart of him to plant the camera (lol, sorry no pun intended). But the one very wrong thing he did was to keep his baby daughter in the apartment. He should have made up a lie and said his wife and baby were going away to visit relatives. Babies are far more vulnerable than adults. I really hope she didn't suffer any permanent damage.
