Toxic Relationship Leads to Crime Case- The Disturbing Case of Travis Alexander and Jodi Arias

From the start of their courtship, friends say, Jodi Arias and Travis Alexander had a potent chemistry.
Arias, 26, was a blonde, beautiful and seemingly carefree aspiring photographer. Alexander was a 29-year-old motivational speaker, salesman and devout Mormon.
Friends said the connection was instant when they met.
"She was really excited about the relationship. She loved how funny he was, how much fun they would have together. Travis loved to take adventures and do different things," said Alexander's friend Sky Lovingier Hughes.
Although they lived in different states -- he was in Mesa, Arizona, and she was in Palm Desert, California -- they maintained a long-distance relationship for a few months and would meet at the Murrieta, California, home of Lovingier Hughes and her then-husband Chris Hughes.
But Alexander’s friends told "20/20" that they started noticing red flags with Arias early on in the relationship. They said they’d alerted Alexander to their concerns and that they'd even grown concerned for his safety as things grew toxic and volatile between the two
