The Menendez brothers’ abuse allegations center on Lyle and Erik Menendez’s claim that their father, Jose Menendez, sexually, physically, and psychologically abused them for years, and that their mother, Kitty, knew and did nothing. Both brothers admitted shooting their parents inside the family’s Beverly Hills home on August 20, 1989, but said they acted out of fear built up over a lifetime of that abuse. The claims split the jurors at their first trial, were largely blocked from shaping the verdict at the retrial that convicted them in 1996, and resurfaced decades later alongside new evidence that led to their May 2025 resentencing.
What the Brothers Said Happened
Lyle testified that Jose began sexually abusing him when he was six, starting with fondling and escalating to rape. Erik testified that the abuse never stopped for him, and that he did not tell Lyle until he was eighteen, just days before the killings. Both described Jose as controlling every part of their lives, from grades to friendships, and punishing any deviation severely.
Their mother, they said, was not a passive bystander. They testified that Kitty knew about the sexual abuse and did nothing to intervene.
On the night of the shootings, the brothers said they had reached a breaking point. Lyle had recently confronted Jose about abusing Erik, and they believed their parents would kill them to keep the family’s secrets from getting out. They retrieved shotguns, walked into the television room, and opened fire. They have maintained ever since that it was self-preservation, not premeditation.
Who Else Backed Up the Account
Two relatives corroborated parts of the brothers’ story at trial. Cousin Diane Vandermolen testified that when Lyle was about eight, she told Kitty directly that something inappropriate was happening between Jose and the boys, and that Kitty refused to believe her. Another relative, Alan Andersen, testified that Kitty would not console the children and that he was kept away from the bedroom area when the boys were alone with their father.
The defense also leaned on expert testimony. Its experts described what they called “battered person syndrome,” arguing it was the functional equivalent of battered woman syndrome applied to abused children, and that years of violence had conditioned the brothers to read an ambiguous word or gesture from Jose as a lethal threat. Prosecution expert Melvin Guyer, a University of Michigan psychologist, called the syndrome a “catchall for impressionistic clinical judgments” with no formal diagnosis in the scientific literature. Under cross-examination, defense experts conceded the point.
Defense attorney Leslie Abramson, who represented Erik, framed the brothers in the press as damaged children rather than killers. “These are not murderers,” she said. “These are troubled kids in a very difficult and grotesque home environment, and they cracked.” Abramson was later investigated for allegedly asking a psychiatrist to alter his notes; prosecutors declined to bring charges, citing insufficient evidence.
How the Courts Treated the Abuse Defense
The abuse claims had very different legal weight in the two trials.
The First Trial: Juries Split
The 1993–94 trial used two juries, one for each brother, because some evidence was admissible against only one defendant. Judge Stanley Weisberg allowed the defense to argue imperfect self-defense, a California doctrine that permits a voluntary manslaughter conviction instead of murder when a defendant honestly believed they were in danger, even if that belief was objectively unreasonable.
Neither jury reached a verdict. On Erik’s panel, six jurors favored manslaughter for the killing of Jose and five favored first-degree murder. On Lyle’s panel, six voted for manslaughter in Jose’s killing and three for first-degree murder. The splits were similar on the charges tied to Kitty’s death. Weisberg declared mistrials, Erik’s on January 13, 1994, and Lyle’s on January 28. About half of each jury had found the abuse claims credible enough to reduce the charges.
The Retrial: The Defense Was Boxed In
The 1995–96 retrial looked different. Weisberg let the defense raise abuse in general terms but imposed strict limits. He cut back sharply on the family members, teachers, coaches, and friends who had testified for weeks the first time around, calling much of that testimony irrelevant. He then ruled, after a series of hearings, that the jury could not reduce murder to manslaughter based on the abuse claims. He found insufficient evidence that the brothers faced imminent danger on the night of the shootings, which effectively eliminated the imperfect self-defense theory that had divided the first juries.
With manslaughter off the table, the jury was left with first-degree murder, second-degree murder, or acquittal. On March 20, 1996, both brothers were convicted of first-degree murder and conspiracy to commit murder, and sentenced to life without the possibility of parole. Prosecutors later said the narrowed jury instructions were the decisive factor.
Evidence That Surfaced Later
Two pieces of evidence relevant to the abuse claims came out long after the convictions.
The first is a letter Erik wrote to his cousin Andy Cano in 1988, roughly eight months before the murders, discovered in a box of old family correspondence. In it, Erik wrote: “It’s still happening Andy but it’s worse for me now. He’s warned me a hundred times about telling anyone, especially Lyle.” The letter predates the killings and the arrest, which makes it harder to dismiss as a story built after the fact.
The second came from Roy Rosselló, a former member of the 1980s boy band Menudo. In a 2023 Peacock documentary, Rosselló alleged that Jose Menendez had sexually assaulted him as a teenager during his time with the group. He later filed a lawsuit alleging multiple assaults at Menendez’s New Jersey home, at a New York hotel, and in Brazil. His account offered an allegation of sexual abuse by Jose from someone entirely outside the family, a form of corroboration that did not exist at either trial.
Where the Abuse Claims Stand Now
The new evidence opened two legal tracks. In May 2023, defense attorneys filed a habeas corpus petition arguing the Cano letter and Rosselló’s allegations were new evidence that could have changed the trial’s outcome. Separately, the Los Angeles County District Attorney’s office began reviewing whether resentencing was appropriate.
In October 2024, then–District Attorney George Gascón announced he would recommend resentencing, citing a review of the new evidence, the brothers’ rehabilitation across more than three decades in prison, and a deeper modern understanding of sexual violence than existed at the time of the original prosecution. His office noted both brothers had mentored other inmates, pursued education, and kept clean disciplinary records.
When Nathan Hochman replaced Gascón, he moved to withdraw the resentencing recommendation, arguing that the brothers had never taken “full responsibility” because they continued to maintain they acted in self-defense. He called their continued self-defense claims “lies, deceit, and perjury.” The court went forward with resentencing anyway. In May 2025, a judge resentenced both brothers to 50 years to life, making them eligible for parole for the first time.
The habeas petition did not fare as well. On September 17, 2025, Judge William C. Ryan denied it, ruling that the new evidence would not have created reasonable doubt for even one juror and did not negate the original findings of premeditation and lying in wait. The resentencing stands independently of that ruling, so parole eligibility is unaffected, but as a legal matter the abuse allegations have not reopened the murder convictions themselves.
