On the morning of February 8, 1983, a plumber working in London’s Muswell Hill neighbor opened a drainage cover behind a Cranley Gardens apartment building and made a horrific discovery—the drain was blocked by pieces of bone and human tissue. Upon investigation, detectives traced the blockage back to one apartment in the building, where additional evidence suggested things were far worse than they’d initially thought.

When the occupant of the apartment, Dennis Nilsen, was confronted with the human remains, he began telling investigators a shocking story and when he was finished, Nilsen had confessed to murdering and dismembering at fifteen men over the course of five years. 

In the annals of British crime, Dennis Nilsen ranks among the worst serial killers the country has ever seen, not only because of the number of people he killed, but also the method of disposal and the motive.
