About 48 Hours Season 24, Episode 23 : The Stranger Beside Me

Jamie, a graduate of the University of Michigan, moved to Phoenix and got a high-paying job in medical sales. When she joined a local university alumni group, Jamie fell for a handsome young member named Bryan Stewart. The couple dated for a year and lived together for two. Then Jamie went missing. While searching for her, detectives found evidence that Bryan had been lying to Jamie, and police, about who he is. Bryan is actually Rick Wayne Valentini. Ten years ago he changed his identity illegally, and moved from Michigan to Phoenix to "start over." But the life he left behind led detectives to suspect that Bryan is more than just a con man. In his only interview, the man who insists he is Bryan Stewart talks with 48 HOURS MYSTERY correspondent Erin Moriarty about changing his name, his relationship with Jamie and his claim that he helped her disappear. The broadcast also features exclusive interviews with Jamie's family and friends, Bryan's aunt and daughter, and lead investigators in the case.
