(NewsNation) — Los Angeles County District Attorney Nathan Hochman, who opposes releasing Erik and Lyle Menendez from prison, says his office submitted an analysis of more than 80 pages to California parole officials mapping out how the brothers brutally murdered their parents in 1989.

The siblings are going before parole panels, separately, this week. Erik Menendez, 54, was up first, and was denied parole; 57-year-old Lyle and his advocates were slated to make their case Friday, with Gov. Gavin Newsom having the ultimate say on any recommendations for release.

Hochman has said the Menendez brothers have never accepted responsibility for their actions even as supporters argue the siblings have been redeemed behind bars and helped other inmates.
