Diane Michelle Zamora (born January 21, 1978) is a former United States Naval Academy midshipman and convicted murderer who, in 1995, murdered Adrianne Jessica Jones, who she believed was a romantic rival for her ex-fiancé and accomplice, David Graham. Graham had confessed to giving Adrianne a ride home and having sex with her one month earlier, leading an enraged Zamora to demand that he kill Jones. In the early morning of December 4, 1995, Graham picked up Jones in Zamora's car while she hid in the hatchback. They went to a remote location and got into a struggle, at which point Zamora hit Jones over the head with weights and Graham shot her twice after she broke away from them.
