Rick Valentini has been serving time in a Florence prison for the murder of his ex-girlfriend, Jamie Laiaddee. She was reported missing in May 28, 2010.

Valentini claims she left for a job interview in Denver, Colorado and never returned. He says he doesn’t know what happened to Laiaddee.

“I have no clue,” says Valentini. “All I can tell you is I’ve never killed anyone in my life and I maintain that to this day.”

Laiaddee’s friends paint Valentini as a conman and controlling sociopath. They believe Valentini snapped because Laiaddee broke up with him and she was paying most of his bills.

Valentini argues he had a downtown Phoenix condo when they met and he was not financially dependent on Laiaddee.

“The only reason that we agreed to move in together is that it just saved money,” says Valentini.

Valentini met Laiaddee through a University of Michigan alumni group. It would later be revealed that Valentini had no ties to the college and he was using a false identity.

“You don’t actually have to graduate from Michigan to be in the alumni club,” argues Valentini. He claims his forged diploma was a gag gift from a friend.

Laiaddee knew Valentini as Bryan Stewart, which Valentini claims was a name he chose following a history of family disputes over his original name.

“My mother had lied on the birth certificate,” says Valentini.

Valentini says he plans to appeal his conviction.
