As Bill interrupts to show them a newspaper article, the team is discussing a killer in the conference room and Holden mentions that making furniture out of human remains qualifies as "organized behavior". This references killer, Ed Gein, one of the most notorious killers of all time. After the death of his mother, he began grave-robbing, making furniture, clothing, and other trophies from human bones and skin. A number of famous movie characters are modeled on Gein, such as Norman Bates in Psycho (1960), Leatherface in The Texas Chain Saw Massacre (1974), and Buffalo Bill in The Silence of the Lambs (1991).
