Ryan Murphy’s ‘Monster’ Season 2 Casts Cooper Koch, Nicholas Alexander Chavez as the Menéndez Brothers

Cooper Koch and Nicholas Alexander Chavez have been cast in Season 2 of Ryan Murphys Monster, Variety has learned. They will play the Menndez brothers in the Netflix anthology series, which told the story of Jeffrey Dahmer (Evan Peters) in Season 1.

Netflix confirmed the subject and title of Monsters: The Lyle and Erik Menendez Story in May. This will be the first of the two additional Monster installments that Netflix ordered after Dahmer The Jeffrey Dahmer Story became the streamers No. 2 most popular English-language series of all time. (It was surpassed by Wednesday in December; then recently, Netflix began ranking viewership by estimated viewers instead of total hours viewed, putting Dahmer at No. 3 behind Wednesday and Stranger Things Season 4.)

Erik (played by Koch) and Lyle Menndez (Chavez) were convicted of the murders of their parents, Jos and Mary Louise Kitty Menndez, in 1996. The brothers eventually confessed, but maintained that they killed their parents out of fear after being abused. Recently, former Menudo band member Rossell also made sexual assault allegations against Jos Menndez, which were explored in the Peacock docuseries Menendez + Menudo: Boys Betrayed.

Kochs acting credits include two episodes of Power Book II: Ghost in which he played Chase, with additional appearances in the 2022 films Swallowed and They/Them.

Chavez currently stars in General Hospital, having played Spencer Cassadine for more than 250 episodes. He also played Jason in the 2022 film Crushed.

Netflix did not immediately respond to Varietys request for comment. Deadline was first to report the news.
