Forensic psychologist Dr. Eric Hickey had a conversation with the late Joyce Dahmer about Jeffrey Dahmer, the notorious serial killer who murdered at least 17 people between 1978 and 1991. Hickey stated that Dahmer felt badly about himself, not the victims, but about his own life. Dahmer's mother reportedly confided in Hickey about her son's dark and twisted behavior, including looking for bodies in newspapers and attempting to dig them up at night to be with someone else. Hicic also mentioned that Jeffrey had built a table with eight heads and a black chair facing outward from the Hellraiser film franchise.
