The new season of the Netflix series chronicles the real-life 1996 murders of José and Mary Louise "Kitty" Menendez by their two sons. The brothers have long claimed their actions came after years of physical, emotional and sexual abuse, while prosecutors argued they were after their parents' money. Starring Javier Bardem (José Menendez), Chloë Sevigny (Mary Louise “Kitty” Menendez), Cooper Koch (Erik Menendez), and Nicholas Alexander Chavez (Lyle Menendez), the show premieres Thursday, September 19 on Netflix.
