Have Erik and Lyle Menendez been rehabilitated during 30-plus years in prison? That's the question at the center of this week's two-day court hearing in Los Angeles.

Erik and Lyle Menendez are seeking what could amount to the end of their life terms in the 1989 murders of their parents, though the district attorney is against that outcome.

Defense attorneys for Erik and Lyle Menendez are hoping to win a reduced sentence for the brothers, possibly allowing them to either be released immediately or at least eligible for parole consideration.
