The Menendez brothers' uncle is asking the court to keep them behind bars

LOS ANGELES (KABC) — Los Angeles County District Attorney George Gascón's decision to seek resentencing for Lyle and Erik Menendez brought relief to some members of the brothers' extended family.

The Menendez brothers were sentenced to life in prison without the possibility of parole in 1996 for the 1996 murders of their parents Jose and Kitty Menendez at the family home in Beverly Hills.

Not everyone in the Menendez family is happy with the prosecutor's call.

An attorney for Milton Andersen, the 90-year-old brother of Kitty Menendez, filed an amicus brief with the court to present the other side to Gascón's request for resentencing. Andersen tries to keep the brothers' original punishment.

“They shot their mother, Kitty, while she was reloading to ensure her death,” Andersen’s attorney, Kathy Cady, said in a statement Thursday. “The evidence remains overwhelmingly clear: the jury’s verdict was fair and the sentence fits the heinous crime.”

Mark Geragos, an attorney for the brothers, declined to comment on the statement from Andersen's lawyers.

Cady told Eyewitness News that Gascón's decision was a “clear ploy to gain additional votes before the election.”

Cady says Gascón's office consistently excluded Andersen from the review process – a violation of California law.

“He’s disappointed,” she said. “He believes that justice was served when Lyle and Erik were convicted of murder and special circumstances and that their sentence was appropriate.”
