The break of the Menendez brothers case was an unlikely suspect. She was a woman by the name of Judalon Smyth who was having an affair with the married psychologist, Dr. Jerome Oziel, who had been treating Erik Menendez. Smyth went to the cops days after her affair with Oziel ended.
Smyth told police Oziel had a recording of the brothers confessing to their parent's murders.
After the murders, Erik Menendez went to Oziel for therapy. He was struggling with guilt and was considered suicidal.
"Almost had no choice to do what I did. And I hate myself for doing it," Lyle said in the recording, "I did what I thought my mother would want me to do, which is please kill me."
The brothers spoke extensively about their mother's despair over her husband's extra-marital affairs and her suicide attempts.
Now 28 years later, from behind bars at Mule Creek State Prison, Lyle Menendez spoke with NBC4 about the so-called "confession."
Erik Menendez testified that Oziel suggested both brothers make a recording so he would feel "comfortable" and "would no longer go to the police."
But for the lead detective on the case, the tape is more significant for what is not said.
Now serving a life sentence with no chance of parole, Lyle Menendez explains why they did not tell Oziel what motivated them to kill their parents.
"I kinda was hoping that maybe like with my father's death the secrets of my past sorta died with me," Lyle admitted. "I can't really express enough how, that private shame, how shameful, you just don't talk about this kind of toxic things that have happened to you. You just don't."
