Peters, one of Murphy's go-to actors, will play the notorious serial killer in Monster: The Jeffrey Dahmer Story, from Murphy and his collaborator Ian Brennan. Also joining the cast are Niecy Nash, Penelope Ann Miller, Shaun Brown and Colin Ford. They join the previously cast Richard Jenkins, who will play Dahmer's father. Miller will portray Dahmer's mother, while Nash will take on the female lead role of the serial killer's neighbor "who called police numerous times and even tried calling the FBI to alert them of Dahmer’s erratic behavior, to no avail," according to Deadline. Brown portrays Dahmer's last intended victim. This is the second time Murphy has had to cast an actor to play Dahmer. Seth Gabel played Dahmer in two episodes of American Horror Story: Hotel. As Deadline notes, "Monster chronicles the story of one of America’s most notorious serial killers (Peters), largely told from the point of view of Dahmer’s victims, and dives deeply into the police incompetence and apathy that allowed the Wisconsin native to go on a multiyear killing spree. The series dramatizes at least 10 instances where Dahmer was almost apprehended but ultimately let go. The series also is expected to touch on white privilege, as Dahmer, a clean-cut, good-looking white guy, was repeatedly given a free pass by cops as well as by judges who were lenient when he had been charged with petty crimes."
