The Worst Things Necrophiliac Serial Killer Dennis Nilsen Did To His Victims

Serial killer Dennis Nilsen is one of the most notorious British serial killers to have ever lived. Between 1978 and 1983, this North London resident killed between 12 and 15 young men. He strangled some, drowned others, dismembered their bodies (but not before performing sexual acts on some of them,) and then disposed of their remains in various ways.

Nilsen, as with most serial killers, has a number of nicknames. He is also known as the Kindly Killer and the Muswell Hill Murderer, based on the ways in which he picked up his victims and the place where he lived when he killed them. Some also call him the British Jeffrey Dahmer

The gruesome details of Dennis Nilsen's crimes are horrifying and have captured the fascination of people worldwide. This necrophiliac killer was demented and twisted in more ways that one.

  • He Killed Between 12 And 15 People - But Possibly Has More Victims

    Nilsen's final body count stands between 12 and 15. He was unable to name all of his victims, and it is possible that he made up some of them.

    Either he truly did not remember killing them, or he was trying to prove that he was insane, and therefore nor fully liable for the murders attributed to him. Some speculate he could even have killed more people than he claimed. 

  • He Was A Necrophiliac

    He not only murdered the young men he lured into his house, dismembering their bodies and stashing them in various places, but he also performed sexual acts with at six of their dead bodies.

    He stated on the stand that before he even began killing, he fantasized about having sex with passive, unconscious, and even dead bodies.

    Nilsen began his murderous spree in 1978. At the time, he lived in a house at 195 Melrose Avenue in North London. While there, he killed at least 12 men, depositing their remains in various places around the structure. He removed their organs and threw them over the back fence, burned some body parts in a bonfire, and most horrifically, stashed bits of his victims underneath the floorboards of his bedroom.

    Before he moved out of the house, he removed the remaining body parts and burned them in the backyard, masking the smell by burning an old tire along with them.

    Malcolm Barlow was a 23-year-old man killed by Nilsen on September 18, 1981. Nilsen ran into Barlow the previous day in an alley. In a twisted act of kindness, Nilsen helped Barlow get to the hospital, who was having a reaction to his medication.

    After Barlow left the hospital, he went straight to Nilsen's house in order to thank him. Instead, Nilsen fed him dinner and then strangled him to death. Since Nilsen had no more room under the floorboards for another body, he instead stashed Barlow's remains under his kitchen sink.

    Graham Allen was Nilsen's second to last victim. He met Allen while hailing a cab, and lured him to his home with the promise of a good meal and some company. Instead, Nilsen cooked Allen an omelet and then strangled him with a ligature while he was eating. Allen's body then sat in Nilsen's bathtub for several days before dissecting him on the kitchen floor and sending his remains down the drain.

    After Nilsen's arrest, when the authorities tested the odd flesh and bone fragments that plugged up the drains, they found DNA evidence that matched Allen.

    Stephen Sinclair was Nilsen's last victim. He was killed on January 26, 1983. Sinclair came home with Nilsen, and together they listened to music. Sinclair fell asleep, and Nilsen strangled him with a necktie before bathing his body and applying talcum powder. He then laid Sinclair out on his bed, arranged three mirrors around the space, and then fell asleep next to his dead body. 

    Later, after his arrest, Nilsen said he was in love with Sinclair and could feel him with him in his cell.
