Their mothers are gone, why 😢 ?

I don't think anyone can get to the bottom of it - this is the strangest mystery since documentation first began in 2016 - the synchronous disappearance of two females who we have been watching since the day they were born. They were both thriving and in their prime by the time they suddenly vanished without a trace. Can we finally make some sense out of it ? Can we ever get a closure ?
