Prosecutors in Los Angeles are reviewing new evidence that could lead to the release or a new trial in the case of two brothers who were convicted of killing their parents in their Beverly Hills mansion.

Lyle Menendez, 56, and his 53-year-old brother Erik are serving life in prison without parole for the 1989 shotgun murders.

Their father and mother – Jose and Kitty Menendez – were shot several times at close range. Lyle was 21 and Erik was 18 at the time.
