In the early 90s, the Menendez brothers, Lyle and Erik, became household names after their murder case and trial was broadcast across the nation.
The notorious brothers were found guilty for murdering their wealthy parents, Jose and Kitty Menendez, with a shotgun in their Beverly Hills home in 1989.
At the end of what was dubbed "trial of the century," Lyle and Erik were both sentenced to life in prison without parole in separate facilities.
Over the years, the Menendez case inspired documentaries, TV show plots and biopics, including the 1994 made-for-TV movie Menéndez: A Killing in Beverly Hills, and more recently, a documentary titled Truth and Lies: The Menéndez Brothers - American Sons, American Murderers.
Lyle, the eldest, has often spoken with the media and expressed regret for his actions. Just this past September, he was called into Megyn Kelly TODAY from prison for an interview.
"It's really, a regret every day, a regret every day, but at the same time, I can't escape what happened anymore than I can escape the memories of what happened to me," said Lyle, who is currently detained at Mule Creek State Prison in Ione, California.
Lyle still maintains that although the crime was not premeditated, he could no longer handle the abuse he and Erik suffered at the hands of their father.
"There really wasn't a discussion about killing my parents," he said. "I didn't know the details of what had happened between my brother and my father, and when I first heard about it, I had some of the same reaction that some people have, 'How could you not have resisted? Why didn't you tell me? Why didn't you run away? Why didn't you fight back against your father.'"
Now, for the first time in a decade, Erik is also breaking his silence on the chilling murders he's committed to share the "truth" about the entire situation.
