The Menendez brothers who were prison for murdering his parents 35 years ago should not be released, their uncle has said.

Erik and Lyle Menendez shot their parents in their Beverly Hills mansion in August 1989, before calling 911 and claiming to have discovered their bodies.

The couple were sentenced to life in prison without parole after admitting the murders, but said they had acted in self-defense after years of sexual, physical and psychological abuse by their father, Jose.

On Thursday, prosecutors recommended that the brothers be resentenced to 50 years in prison with the possibility of immediate parole, meaning a judge’s ruling could possibly see them walk free within months.

However, Milton Andersen, the 90-year-old brother of Mary “Kitty” Menendez, the mother of the Menendez brothers, has opposed the release of his nieces and nephews after 35 years behind bars.

His lawyer, Kathleen Cady, on Mr. Andersen’s behalf accused George Gascon, the Los Angeles County district attorney who recommended the brothers’ release, of “turning a blind eye to potential flaws in his quest to rewrite history.”

The case received renewed attention recently after Netflix released a drama and a separate documentary about the family, which exposed allegations of sexual abuse and prompted calls for the case to be re-examined.

The new evidence includes a letter written by Erik Menendez that his lawyers say corroborates allegations that he was sexually abused by his father.

Speaking to CNN, Cady cast doubt on the new evidence of sexual abuse, describing it as “theoretical.”

“The sentence was appropriate and should stay,” she said, adding that she had “received emails claiming that the letter was written (after)” the brothers were sentenced.

The lawyer also said it was “somewhat suspicious” that Mr Gascon had requested the brothers be re-sentenced in the middle of his re-election campaign, suggesting there may be a political motivation behind the timing.

The prosecutor currently trails Nathan Hochman, his more conservative opponent, in the polls by 30 points and has faced a barrage of criticism over his progressive overhaul of the district attorney’s office.

Mr Hochman has attacked his opponent over the move, accusing him of casting “a cloud over the fairness and impartiality” of the case and “destroying himself to grab headlines through a televised decision”.
