Part 2 of 3) 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.

In the early hours of March 3, 1993, someone snuck into the Maryland home of Millie Horn, where she lived with her disabled eight-year-old son, Trevor, and his nurse, Janice Saunders. After shooting both women in the head multiple times, the intruder smothered Trevor Horn to death, then quietly left the house. Hours later, the bodies of all three were discovered by Millie’s sister, who stepped by to check on them.

Almost immediately, suspicion fell on Millie Horn’s ex-husband, Lawrence, who lived thousands of miles away in California, but with whom she’d spoken just hours before the murders occurred. In time, investigators were able to establish a financial motive, linking Lawrence Horn to the murders, yet they were unable to place Horn in Maryland when the murders occurred.

Ultimately, Lawrence Horn would be tried and convicted for all three murders, but by that time, he wasn’t sole perpetrator of the crime. And when prosecutors were finally able to pin down the men responsible for the deaths, it turned out the killers received guidance from a very surprising source.
