Nick sat down with Chicago lawyer Karen Conti, the attorney who represented serial killer John Wayne Gacy during his final years on Death Row. As Gacy’s attorney, Karen got closer to him than almost anyone else (even keeping some of his infamous Clown paintings) and came to understand the personality, behaviour, manipulation, and final days of one of America’s most notorious serial killers.

Karen discusses their first meeting, Gacy’s disturbingly calm demeanour, the legal fight to save him from the death penalty, and the unsettling practical joke he arranged for her after his execution. Karen's insights shed new light on one of America’s most infamous serial killers and the psychology behind his crimes.
