Erik and Lyle Menendez have created self-help groups and programs while locked up for 35 years

LOS ANGELES — Erik and Lyle Menendez have lived more time behind bars than free.

Since their arrest over 35 years ago for the double murder of their parents in their Beverly Hills, California, home, the brothers have gotten an education, participated in self-help classes and started various support groups for their fellow inmates.

Their attorneys plan to highlight their behavior during their time in prison when they argue before a Los Angeles judge on Thursday and Friday for a reduced sentence that could lead to their release.

The brothers were sentenced to life in prison without the possibility of parole at ages 18 and 21 after killing their entertainment executive father, Jose Menendez, and their mother, Kitty Menendez.

While defense attorneys argued the brothers acted out of self-defense after years of sexual abuse by their father, prosecutors said the brothers killed their parents for a multimillion-dollar inheritance.

Former District Attorney George Gascón gave them another chance when he asked the court to consider a new sentence for the brothers, one that would make them immediately eligible for parole.

A resentencing petition filed by Gascón's office gives a detailed view of their time locked up and their efforts at rehabilitation. Both brothers have received commendations and statements of support from correctional officers who have observed their behavior in prison.

''As far as I can perceive from my professional training as a correctional peace officer, Erik Menendez is a rehabilitated man who humbly strives toward helping those in need,'' Corrections Officer D. Rosario said in a March 2016 memo, according to the resentencing petition.

Gascón's successor, Nathan Hochman, doesn't agree. He submitted a motion last month to withdraw the resentencing request, and prosecutors argued during last Friday's hearing they could not support the brothers' resentencing.

Disciplinary records

Lyle has not been in a single fight in the 30 years he has been in prison, according to prison records that noted that he had to be moved to a Special Needs Yard in 1997 because ''he wouldn't fight back when attacked."

Both brothers have the lowest possible risk assessment and raw security risk scores for inmates serving a life sentence, according to the resentencing petition.

Early prison years

During the first few years of his time in prison, Erik completed numerous victim empathy, anger management and domestic violence programs.

Lyle became involved in leadership roles early on and served as Representative for Prisoners in Northern California prisons in 2003, according to associate warden B. Holmes in a 2017 memo cited in the resentencing petition.

''For over 10 years serving in that capacity, he has worked productively with the administration to foster a positive programming culture at Mule Creek State Prison," Holmes said.

Community support groups

''Because even behind bars, he believes in compassion and dignity,'' his cousin Anamaria Baralt said at a news conference last month.

According to community resource manager Crystal Lopez, Erik authored the whole curriculum and eventually developed a new 126-page manual for the program in 2023.

Erik also started two meditation programs and has become the lead facilitator for Alternatives to Violence, an in-prison conflict resolution workshop. At one point, he was teaching five different classes a week, the resentencing petition said.

Lyle founded a program in 2016 that focuses on helping other inmates understand their childhood trauma and discuss topics like experiencing sex abuse as children as well as Youth LWOP Ally, a mentorship group of youth offenders with sentences of life without possibility of parole mentoring other youth working on their rehabilitation goals.

The Green Space Project

Their project was inspired by the Norwegian approach to incarceration that believes humane prison environments leads to more successful reintegration into society.

''Over 100 inmates participated, marking the first time prison administration entrusted an inmate to lead such a redesign,'' Baralt said during a virtual news conference in February.

He worked with local businesses and all levels of prison administration to raise more than $250,000 for the project, and he partnered with Guide Dogs of America to raise $100,000 for artificial grass, according to the resentencing petition.

Erik is the lead painter for a massive mural that depicts San Diego landmarks.

The final product will include outdoor classrooms, rehabilitation-group meeting spaces and training areas for service dogs.

Lyle graduated from the University of California, Irvine with a bachelor of arts in sociology earlier this year and earned an associate degree in sociology previously. He is currently enrolled in a master's program where he studies urban planning and recidivism, and the Green Space program is part of his capstone project.

Erik was accepted into UC Irvine for the fall 2023 term and will graduate in June with a bachelor of arts in sociology. Prior to that, he earned associate degrees in sociology and social and behavioral science, as well as a health care aide diploma.
