LOS ANGELES — A judge was set to decide Monday whether new evidence warrants a reexamination of the convictions of Erik and Lyle Menendez in the shotgun deaths of their parents in their Beverly Hills home more than 30 years ago.

The brothers were found guilty of murdering Jose and Kitty Menendez in 1989 and sentenced to life in prison without parole. While their defense attorneys argued at trial that they had been sexually abused by their father, prosecutors denied that and accused them of killing their parents for money. In the years that followed, they repeatedly appealed their convictions without success.

Now, at 53 and 56, Erik and Lyle Menendez are making a new bid for freedom. Their lawyers filed a habeas corpus petition — a request for a court to examine whether someone is being lawfully detained — in May 2023, asking a judge to consider new evidence of their father’s sexual abuse. “Newly discovered evidence directly supports the defense presented at trial,” the petition said.

The releases of the Netflix drama “Monsters: Lyle and Erik Menendez Story” and the documentary “The Menendez Brothers” this year brought renewed public attention to their plight.

Prosecutors recommended resentencing for the brothers last month, saying they have worked on redemption and rehabilitation and demonstrated good behavior inside prison.

Los Angeles District Attorney George Gascón held a news conference less than two weeks before Election Day, asking for new sentences of 50 years to life. This could make them immediately eligible for parole because they were younger than 26 when they killed their parents.

The brothers’ extended family has said they deserve to be free after decades behind bars. Several family members have said that in today’s world — which is more aware of the impact of sexual abuse — the brothers would not have been convicted of first-degree murder and sentenced to life.

Not all Menendez family members support resentencing. Attorneys for Milton Andersen, the 90-year-old brother of Kitty Menendez, filed a legal brief asking the court to keep the brothers’ original punishment. “They shot their mother, Kitty, reloading to ensure her death,” they said in a statement Thursday. “The evidence remains overwhelmingly clear: the jury’s verdict was just, and the punishment fits the heinous crime.”

Superior Court Judge Michael Jesic is scheduled to consider the resentencing request on Dec. 11, but he’ll first address the abuse evidence raised in the habeas petition. Immediate freedom is one possible result; the judge also might weigh in on the merits of the evidence. And if the brothers don’t get relief in court, they can hope that California’s governor will grant them clemency.

The new evidence includes a letter Erik Menendez wrote in 1988 to his uncle Andy Cano, describing the sexual abuse he had endured from his father. The brothers asked their lawyers about it after it was mentioned in a 2015 Barbara Walters television special. The lawyers hadn’t known of the letter and realized it had not been introduced at their trials, making it effectively new evidence that they say corroborates allegations that Erik was sexually abused by his father.

More new evidence emerged when Roy Rossello, a former member of the Latin pop group Menudo, recently came forward saying he had been drugged and raped by Jose Menendez, the boys’ father, when he was a teen in the 1980s. Menudo was signed under RCA Records, where Menendez was chief operating officer.

Rossello spoke about his abuse in the Peacock docuseries “Menendez + Menudo: Boys Betrayed” and provided a signed declaration to the brothers’ lawyers.

Had these two pieces of evidence been available during the trial, prosecutors would not have been able to argue that there was no corroboration of sexual abuse, the petition says.
