Los Angeles County District Attorney George Gascón said his office is actively reviewing the case of Erik and Lyle Menendez, who were convicted of killing their parents in Beverly Hills in 1989, in light of renewed allegations of sexual abuse by their father,

The evidence prosecutors plan to consider includes a letter allegedly penned by Erik Menendez eight months before the murders and claims by another man that Jose Menendez sexually assaulted him in the 1980s.

Erik and Lyle Menendez were convicted and sentenced to life in prison without the possibility of parole. Los Angeles prosecutors said this week they are taking another look at the case.
