How Was Serial Killer John Wayne Gacy Caught?| The New Detectives | Real Responders

This week we explore the art of mind hunting; profilers detail how they use the science of the mind to track down killers. Forensic scientists work with a variety of methods (i.e. computer technology, anthropology, entomology) to solve crimes which would otherwise remain unsolved, through finding seemingly obscure clues such as tire tracks, bullet fragments and hair samples and then putting the pieces together. Interviews with forensic pathologists, cold case detectives and victims families show the process entailed in each case. Three separate cases are spotlighted in each episode of this series.
