Snapped

Diane Zamora (1x10)

:

Diane Zamora and her fiancé, David Graham, had a bright future ahead of them. High school sweethearts, the couple had met in 1991 as volunteers in the Texas Civil Air Patrol. She was an honor roll student bound for Annapolis, and he was a track star with an appointment to the Air Force Academy. But their ambitions to serve their country were derailed on December 4th, 1995, when a farmer discovered the battered body of Adrianne Jones, a sophomore member of David's high school track team, laying in a field. Brutally beaten, she had been shot in the head. After nine months of dead ends, investigators got a tip from one of Diane's Annapolis classmates. According to the informant, Diane had admitted that she and David had murdered Adrianne after David had confessed that he'd had sex with the girl. In September of 1996, both Zamora and Graham were arrested for the murder. Given separate trials, the young lovers turned on each other and said that the killing had been the other's idea. Neither defense worked. Both were found guilty and given life sentences.
