The unexpected release of audio from Erik Menendez’s tightly controlled parole hearing last week nearly derailed Friday’s proceedings for his brother, Lyle, and infuriated his family members – who raised questions about the recording’s impact on the outcome and how it was released.

Lyle and Erik Menendez have served more than three decades in prison for the murders of their parents in 1989.

After the board denied his brother parole on Thursday, Lyle Menendez will try to convince a separate panel of commissioners to release him after serving decades in prison for killing his parents. Menendez is scheduled to appear virtually from the Richard J. Donovan Correctional Facility in San Diego on Friday.
