Los Angeles' top cop says he has made a decision on whether his office will seek a sentence reduction for the Menendez brothers.

Erik and Joseph “Lyle” Menendez ambushed their parents with shotguns in the living room of their Beverly Hills mansion in 1989.

Her first trial ended in a mistrial. Both were convicted after their second trial and sentenced to life in prison without the possibility of parole.

However, under a new California law, district attorneys have the authority to seek new sentences imposed before they took office.

The brothers and their supporters, including two dozen relatives, asked Los Angeles District Attorney George Gascon for a resentencing earlier this year, saying new evidence shows the brothers were sexually abused and molested by their father.

The new evidence includes allegations published last year that her father also abused Roy Rossello, a former member of the boy band Menudo, in the 1980s, as well as a letter Erik Menendez wrote to his cousin Andy Cano that surfaced in 2015 be after his death.

The date the letter was written has been questioned by critics of the brothers' possible release. The defense said he sent it to his cousin eight months before the murders.

Gascon is up for re-election in less than two weeks and faces a strong challenge from independent candidate Nathan Hochman, a former federal prosecutor. Critics describe his involvement in the high-profile case as politically motivated. But there is also some public support for the brothers' release after a series of new documentaries, including one on FOX Nation, drew attention to their case.

The brothers fired shotguns at their father, former RCA Records executive Jose Menendez, and their mother, Mary “Kitty” Menendez, as the couple watched television at 10:30 p.m

They ran out of bullets and had to go outside to get more to finish off their mother, who investigators said had blood on the bottom of her shoes, indicating she had tried to escape after the shooting began .

Not all of the brothers' family members support their release.

Kitty Menendez's brother, Milton Andersen, is vehemently opposed to a reduced sentence and on Wednesday asked the judge overseeing the case to keep his nephews in prison for the rest of their lives – as they were originally sentenced .

“Milton Andersen continues to believe that the harassment allegations were fabricated and false, and he believes that the jury returned the correct verdict and the correct sentence was imposed,” his attorney, Kathleen Cady, told Fox News Digital.
