The LA County DA says the Menendez brothers' case is being reviewed for possible harassment amid new evidence

Los Angeles County District Attorney George Gascon said Menendez murder case Two new factors that prosecutors are looking at are being reviewed by his office ahead of a court hearing next month.

Gascon said at a news conference Thursday that there could be a possibility of a mistrial or possibly a new trial. The hearing was held on November 26.

Lyle and Eric Menendez spent nearly 35 years behind bars for fatally shooting their parents, Jose and Kitty Menendez. In the evening at their Beverly Hills mansion August 20, 1989. Prosecutors argued it was a murder motivated by greed – shortly after their parents' deaths, the brothers were accused of spending money on Rolex watches, cars and real estate investments.

But the Menendezes testified that they killed their parents in self-defense. The brothers told the jury about the alleged sexual abuse they said they experienced at the hands of their father during an emotional, highly publicized first trial — each with a separate jury.

With the jurors split, the judge declared a mistrial.

The brothers were later convicted of first-degree murder during a second trial in 1995. Prosecutors argued that the brothers, who were 21 and 18 at the time of the murders, lied about the alleged abuse.

On Thursday, Gascon mentioned a 1988 Letter from Eric Menendez to a cousin that appears to refer to alleged abuse by his father, as well as an abuse allegation made by Roy Rossello, a former member of the boy band Menudo, against Jose Menendez, who worked as a record company executive.

Gascon said prosecutors are reviewing those potential pieces of new evidence as they reconsider the conviction.

Later Thursday, attorney Mark Geragos said at a separate news conference that the new evidence, including a declaration by Rossello, “provides a substantial basis for setting aside the results of the second trial.”

He described the brothers as “model prisoners” during their more than three decades in prison.

“I think we're at a point now where any reasonable person looking at this case believes they should get out,” he said.

The Menendez case has received renewed attention in recent weeks following the release of Netflix's true crime drama series, “Monsters: The Lyle and Eric Menendez Story.” A documentary on the case, “The Menendez Brothers,” premiered Monday on Netflix

Gascon said his office received a lot of calls after the Netflix series was released.

“We are here to tell you that we have a moral and ethical obligation to review what is being presented to us,” Gascon said.
