They were three teenagers with promising lives ahead of them.

Adrienne Jones was a pretty, popular sophomore with an infectious laugh and bubbly sense of humor. She wanted to attend Texas A&M University and become a behavioral analyst. David Graham was a cross-country track star who wanted to become a pilot. His girlfriend, Diane Zamora, was an honor student who had been accepted at the U.S. Naval Academy and hoped to become an astronaut.

But none of those dreams came true.

On Dec. 4, 1995, Jones — known as A.J. to her friends — was found dead in a rural Texas field. She had been hit on the head and shot twice, starting a murder investigation which will be re-examined on Monday night’s People Magazine Investigates, on Investigation Disc

Nearly eight months later, Graham and Zamora were arrested for Jones’ brutal murder. Their motive, prosecutors said: a deadly love triangle. They confessed to the killing, which investigators said Zamora ordered in a jealous rage after she learned that Jones and Graham had once had sex.

The story of teenage love and murder became one of the biggest crime stories of the 1990s and was even made into a TV movie starring Holly Marie Combs.

Zamora and Graham were ultimately convicted in Adrianne’s murder and sentenced to life in prison. (They are both eligible for parole in 2036.)

Despite the conviction, Zamora maintains her innocence in the slaying. While she admits that she witnessed the murder and helped hide it, she insists she never set out to kill anyone.

Now 38, Zamora exclusively speaks out on Monday night’s People Magazine Investigates, on Investigation Discovery, and describes how she felt when Graham cheated on her.

“Anyone who’s ever been cheated on, they know how that feels,” she tells the show. “It breaks your heart.”

The Adriane Jones episode of People Magazine Investigates airs Monday (10 p.m. ET) on Investigation Discovery.
