George Gascón, the Los Angeles district attorney, said on Thursday that his office was reviewing a decades-old case involving the brothers Lyle and Erik Menendez, who killed their parents in their Beverly Hills home and were sentenced to life in prison.
The case in the 1990s was one of the first to draw a daily national audience to a televised criminal trial. By their own testimony, the two young men marched into the den of the family’s mansion one evening with shotguns and fired more than a dozen rounds at their mother and father while the couple sat on the couch.
