The District Attorney said he didn't believe the evidence met the rigorous or narrow standards to either vacate the conviction or give the brothers a retrial.

Lyle and Erik Menendez have been serving sentences of life in prison without the possibility of parole for the1989 murder of their parents, Jose and Kitty Menendez. They still face a resentencing hearing March 20 and 21.

Los Angeles County District Attorney Nathan Hochman said Friday he is asking a judge to deny the Menendez brothers' habeas petition requesting a new trial, potentially eliminating one of three possible tracks to an early release.
