The Corpse Collector | Full Serial Killer Documentary

In 1980s Philadelphia, three separate serial killers roamed the streets of the very same neighbourhood. Having covered the story of The Frankford Slasher, this true crime documentary dives into the story of Harrison Graham – a mentally disturbed serial killer who carried around a Cookie Monster puppet, and kept the bodies of his victims rotting in his own rundown apartment.

Even more chillingly, when finally caught Harrison would go on to claim that while his hands did the killing, he wasn’t the one behind it: instead, a dark, alternate personality living inside of him was the true murderer…

While his crimes aren't as brutal as the “Jack the Ripper” style killings of the Slasher, Harrison’s actions are extremely twisted and disturbing, and to this day it remains unclear as to whether he, or one of his potential alternate personalities, was responsible for the murders.

Often called “The Corpse Collector” or the “Cookie Monster Killer”, let’s see what we make of this complex case together, and its connections to the Heidnik and Frankford Slasher murders!
