"I wanted to go back in time to take everything back that Lyle and I did. It was so wrong," he says.
A&E announced Wednesday that the other Menendez Brother will share his side of the story in an upcoming documentary series called "The Menendez Murders: Erik Tells All."
"For the first time in over a decade, Erik Menendez opens up with his most in-depth interview to date in 'The Menendez Murders: Erik Tells All,' a new documentary series that re-examines one of the most fascinating true crime tragedies of the past century through the lens of one of the convicted killers," reads a press release.
The series will feature extensive phone interviews with Erik, who is heard talking about the recent media attention around the murders of his parents Kitty and Jose in a trailer for the doc.
"I'm Erik Menendez. I'm speaking to you from the Donovan Correctional Facility. I'm serving life in prison without the possibility of parole," he's heard saying. "I've heard many different versions of my life told in the media, and those stories are fictional. I think it's time people hear the truth in my own words without the restrictions of a court room."
"From the moment after, I wanted to go back in time to take everything back that Lyle and I did. It was so wrong," he added. "I didn't want my parents dead, I just wanted the abuse to stop. Years and years of pain exploded that night in an unimaginable violence. It is my own personal hell."
Erik and Lyle brutally murdered their parents in 1989 with two 12-gauge shotguns and later testified that their father sexually abused them. Both are currently serving life sentences, but reportedly play chess through the mail and have "almost never talked" to each other about the murders in the years since.
"My only hope in speaking out is that people may have a more complete understanding. A more complete understanding of the events that led up to my actions on the night of August 20th, and really a fuller picture of what really happened in my life," Erik added in the A&E press release. "All I can hope for is that people will come to realize that the truth is not a simple, one-line explanation that many people have tried to make it out to be. That really, that my life was this unfolding of a complicated life that I lived had all of these things that came into being and that led up to my involvement and responsibility for what is an ongoing and enduring family tragedy."
"The tragedy didn't end on that night, as devastating as that night was. It didn't end there for my family, and it continues on to this day, and that sadness is something that I am trying to make up for with them and with my parents for the rest of my life. It will never end," he added.
The documentary series premieres November 10 at 10pm on A&E.
