() A California state panel on Friday denied parole to Lyle Menendez, a day after parole commissioners voted to keep his younger brother, Erik, behind bars for the Aug. 20, 1989, shotgun murders of their parents.

Details were still trickling out following a daylong and closed parole hearing in which Lyle Menendez and his supporters argued the 57-year-old would not present a danger to the public if released from prison. The Los Angeles County District Attorney’s Office, which opposed parole for the brothers, countered with its own barrage of information about the gruesome murders of Jose and Kitty Menendez.

The Menendez brothers became eligible for parole earlier this year after a judge reduced their sentences from life in prison without the possibility of parole to 50 years to life. Family members of the Menendez brothers say the two have consistently demonstrated remorse and personal growth behind bars over the past three decades.

The California Board of Parole previously assessed the Menendez brothers as having a “moderate risk” of committing violence if they are freed. California criminal defense attorney Brian Claypool said inmates with that risk assessment get paroled only 20% of the time, compared with the two-thirds of “low-risk” inmates who are granted release.

Lyle and Erik Menendez attended their parole hearings remotely from the Richard J. Donovan Correctional Facility near San Diego, where they are housed. Their bids for parole were heard by different lineups of commissioners.

Erik Menendez cited for prison violations

At Erik Menendez’s separate parole hearing Thursday, a California parole commissioner cited several instances of the younger brother breaking prison rules. Offenses ranged from violence to inappropriate behavior with visitors to unauthorized possession of a cell phone.

“Contrary to your supporters’ beliefs, you have not been a model prisoner,” Commissioner Robert Barton told the 54-year-old inmate.

Erik Menendez is next eligible for a parole hearing in three years but can seek an earlier date.

Menendez brothers have never accepted responsibility: Prosecutor

Los Angeles County District Attorney Nathan Hochman has fought efforts to parole the Menendez brothers. He said his office submitted a more than 80-page analysis to state parole officials mapping out how the siblings plotted and carried out their parents’ brutal murders at the family home in Beverly Hills.

The information, he said, reflects prison records of the Menendez brothers, interviews with family members, trial transcripts and gruesome evidence about the way Jose and Kitty Menendez died. The prosecutor says the Menendez brothers have never told the truth about the murders.

“If they ever do it, they might be ready for parole. But they have not done it yet,” Hochman said earlier this week.

He has pushed back at allegations that advocates for the brothers have made, that Erik and Lyle were sexually abused by their father. Hochman said Erik and Lyle Menendez initially made broad self-defense claims that they feared their parents would kill them the day of the murders.

Final arbiter on Menendez case: Gov. Newsom

California Gov. Gavin Newsom, a Democrat and potential 2028 presidential candidate, is considered the final arbiter in the Menendez brothers’ case. His office has broad clemency powers, and the governor is able to reverse decisions by the Board of Parole.

Observers, however, have speculated Newsom would be reluctant to free the brothers because it could negatively impact a bid for the White House.
