Nearly three decades after Erik and Lyle Menendez were sentenced to life in prison for the murders of their parents, a California judge has reopened a door many believed would remain closed.

In 1989, brothers Lyle and Erik Menendez killed their parents by shooting them multiple times at close range at their mansion in Beverly Hills. They were found guilty of first-degree murder and conspiracy to murder in 1996, and sentenced to life imprisonment without the possibility of parole.

The killings of the entertainment executive and his wife in their wealthy Beverly Hills neighborhood were brutal. Their son Lyle Menendez was the one who called 911, with the brothers initially claiming the killing was Mafia-related or connected to their father’s business dealings.
