The Nilsen Files – Dennis Nilsen victims

On February 08 1983, an employee from plumbing service Dyno-Rod found human remains next to a property in Muswell Hill, London.

Dennis Nilsen lived there, and quickly admitted that he was a killer.

The civil servant confessed to having dismembered and murdered a number of vulnerable men he had picked up.

The story was, of course, the subject of the ITV drama Des.

Dennis murdered up to 15 young men and boys over a five year period – from 1978 to 1983.

In those year, Dennis Nilsen brought home 15 victims from London bars.

He strangled and dismembered them, before burying them under his floorboards, in his yard, or even burning their bodies in bonfires.

But it wasn’t until his neighbours called a plumber for their clogged drains in 1983 that human remains were found in the pipes…

In his meagre defence, Dennis Nilsen – who was gay – claims he was sexually abused by his grandfather until he was five years old.

Dennis Nilsen victims – who were they?

Dennis initially confessed to killing 15 young men and boys.

Police searched his home, Cranley Gardens in Muswell Hill, and that of his previous flat in Cricklewood, North London.

They found human organs and torsos in black bin liners, and a severed human head in the kitchen.

Authorities recovered 11 bodies in total.

Sadly, only eight of Dennis Nilsen’s 15 victims have been officially identified.

The youngest of Dennis Nilsen’s victims was only 14.
