The Menendez case involves brothers Lyle and Erik Menendez, who murdered their wealthy parents, José and Kitty, in their Beverly Hills home in 1989. Initially claiming innocence, the brothers were eventually arrested and tried in a highly publicized court case. They alleged years of abuse as their motive, but were ultimately convicted of first-degree murder in a retrial and sentenced to life in prison without parole. The case sparked national debates on family dynamics, abuse, and wealth in the justice system.
