The Menendez brothers were 21 years old (Lyle) and 18 years old (Erik) when they killed their parents in 1989. They were arrested in 1990 and eventually sentenced to life in prison without parole in 1996. In recent years, their sentences were changed to 50 years to life, making them eligible for parole considering their age at the time of the crime, but as of 2025, both have been denied parole in hearings.
