Serial Killers Who Recorded Their Crimes

One of the hallmarks of a serial killer is the collection of trophies. These can be anything that belongs to the victim or reminds the killer of the crime. The Golden State Killer, Joseph DeAngelo, took cufflinks and jewellery from his victims; Dennis “B.T.K.” Rader kept items he stole from victims, along with notes detailing the crime squirreled away in locations he called ‘hidey holes’.
