Ed Gein confessed to killing two women in the 1950s and was accused of digging up corpses and making keepsakes out of human body parts, with his crimes serving as the inspiration for Hollywood horror movies like Psycho and The Texas Chainsaw Massacre.

Each season of Monster is centered on a different real-life killer who made headlines. Season 1 starred Evan Peters as cannibalistic killer Jeffrey Dahmer, with Niecy Nash as suspicious neighbor Glenda. Murphy co-created the series with Ian Brennan and served as showrunner. The season was a big hit, becoming one of Netflix's most-watched series ever with more than 1 billion hours viewed in total. It also earned a number of awards and nominations, including an Emmy for Nash.

Season 2, dubbed Monsters: The Lyle and Erik Menendez Story, debuts this Thursday on Netflix and dramatizes the saga of the Menendez brothers, who became a tabloid sensation when they killed their parents in 1989. Nicholas Chavez and Cooper Koch star as Lyle and Erik, with Javier Bardem and Chloe Sevigny as their parents José and Kitty.
