The upcoming Netflix series 'Monsters: The Lyle and Erik Menendez Story' will explore the notorious case of the Menendez brothers, who murdered their millionaire parents in 1989. Jose and Mary Louise Menendez were shot in their Beverly Hills home, leading to a 1990 arrest of their sons, Lyle and Erik, after their extravagant spending raised suspicions. The brothers claimed they acted in self-defense due to years of sexual abuse from their father, but this was largely dismissed in court, resulting in life sentences without parole. The series features a star-studded cast, including Javier Bardem and Chloe Sevigny, and will premiere on September 19, 2024. Meanwhile, both brothers, now 56 and 53, remain incarcerated at Mule Creek State Prison, with Lyle having been married twice while behind bars. Their attorney argues that gender bias may have influenced their sentencing, suggesting they might have received different treatment if they were sisters.
