Some killers are collectors who obtain perverse gratification by habitually stealing mementos from murder scenes, from jewelry to shoes, keys to even body parts. Others leave their mark at the crime scene, signatures of their personality that create insights into their profile. Each hour-long episode of "Mark of a Killer" follows the story of an investigation guided by the killer's postmortem signature and features first-hand accounts from detectives who worked on the cases as well as interviews with criminal psychology experts and family members and friends of the victims.
