3. Introduction
He was born on November 23, 1945, in Fraserburgh, Scotland.
Nilsen killed his first victim, 14-year-old Stephen Holmes, on 30 December
1978.
Nilsen is believed to have murdered up to 16 vulnerable young men, many of
whom were gay, in north London between 1978 and 1983.
Convicted at the Old Bailey of six counts of murder and two of attempted
murder, Nilsen was sentenced to life imprisonment on 4 November 1983.
Nilsen died in 2018, more than 35 years after being caged for life.
4. Traumatic Childhood
He was born on November 23, 1945, in Fraserburgh, Scotland.
His childhood was traumatic.
His father was alcoholic.
His father and mother continually arguing with each other.
Then, his father moved away when Nilsen was four.
His mother and two siblings then moved into mother’s house.
Nilsen immediately bounded with his grandfather.
When he was only six years old, his grandfather died.
5. Remarriage of Mother
His mother remarried and had four children more.
The situation enhanced his feelings of being left out, alone and uncared for.
He was lost in a crowd.
There was something else that isolated him from his peers.
At a very young age he started to feel romantically attracted to boys.
But though he had feelings, he didn’t act on them.
6. Childhood Behavior
From 1951 Dennis Nilsen became more moody than ever.
His habit of wandering off alone grew compulsive.
And when his mother remonstrated with him and attempted to keep him in,
he responded defiantly that even horses were not tied up.
He also went on long solitary walks.
Dennis felt he could not show his grief at home, where all were preoccupied
with the reorganization of their lives.
He also begun to think as sea his god.
7. “Many years ago I was a boy drowning in the sea. I am always drowning in the
sea … down amongst the dead men, deep down. There is peace in the sea
back down to our origins … when the last man has taken his last breath the
sea will still be remaining. It washes everything clean. It holds within it
forever the boy suspended in its body and the streaming hair and the open
eyes.”
“How to explain the irresistible compulsion to join the sea, to be part of it, to
sink into the solace of its company? His mother would think him mad!”
8. A love for the sea has never ceased to feed his imagination in the years since
he left Scotland.
“In those days I could hate Adam Scott very easily. I was, I suppose, very
jealous of him having a relationship with and the attention of my mother. I
sometimes felt that we, the Nilsen kids, were an impediment to her
fulfilment in her new life and family. I was a very lonely and turbulent child. I
inhabited my own secret world full of ideal and imaginary friends. Nature had
mismatched me from the flock.“
9. It was unfortunate that the Scotts could not tolerate animals of any kind, for
had Dennis been allowed to devote more attention to them he might have
found some relief from the conviction that he was useless.
10. School Life
There was one particular schooldays incident which caused Dennis to
ruminate.
An old man from Strichen, Mr. Ironside, went missing.
Then, his Corp was found.
The boy Nilsen was more perturbed than most by the sight.
‘He reminded me of my grandfather, and the images were fixed firmly in my
mind … I could never comprehend the reality of death.’
In all his years at school, Dennis Nilsen had no sexual encounter, not even of a
minimal kind.
11. However, there was an emotional experience which burned deeply, never to
be released or confessed.
In his sister Sylvia’s class at school there was one boy whom Dennis adored
from afar.
Of the entire school, no other person held this power to make him feel
nervous.
He was, to Dennis, beautiful, enigmatic, different.
12. Dennis felt inferior and ashamed; he did not dare to approach him, but
merely hovered in the playground watching him and trying to get near him,
his legs quivering like jelly.
Whenever he thought of this boy, guilt invaded him, a vague uneasy guilt
without a reason.
13. Employments
For the next three years, from 1961 to 1964, Dennis Nilsen was a boy soldier
at Aldershot.
By his own account, he was ‘a frail and skinny boy, very self-conscious,
introverted, and shy’.
Dennis joined the army catering corps.
He was to learn a skill there that served him well during murderous rampage:
butchering.
Following his departure from army, he joined the police force and stayed for a
year.
14. A special treat for him certainly was access to the morgue and autopsies.
Which fed into the necrophiliac tendencies that had been building inside him
for years.
16. Between 1978 and 1983, Nilsen is known to have killed a minimum of twelve men and boys, and
to have attempted to kill seven others (he initially confessed in 1983 to having killed about
sixteen victims).
The majority of Nilsen's victims were homeless or gay men; others were heterosexual people he
typically met in bars, on public transport, or on one occasion or outside his own home.
All of Nilsen's murders were committed inside the two North London addresses where he resided
in the years. His victims were lured or attracted to these addresses through guile, ypically the
offer of alcohol and or shelter.
17. Inside Nilsen's home, the victims were usually given food and alcohol, then strangled typically
with a ligature, either to death or until they had become unconscious. If the victim had been
strangled into unconsciousness, Nilsen then drowned him in his bathtub, his sink or a bucket of
water before observing a ritual in which he bathed, clothed, and retained the bodies inside his
residences for several weeks or, occasionally, months before he dismembered them.
Each victim killed between 1978 and 1981, their bodies was disposed of via burning on a bonfire.
Prior to their dissection, Nilsen removed their internal organs, which he disposed of either
beside a fence behind his flat or close to Gladstone Park. The victims killed in 1982 and 1983 at
his Muswell Hill residence were retained at his flat, with their flesh and smaller bones flushed
down the lavatory.
Nilsen admitted to engaging in masturbation as he viewed the nude bodies of several of his
victims, and to have engaged in sexual acts with six of his victims' bodies.
18. Late '70s: Nilsen's first would-be
victims escape
According to investigators, Nilsen had formally started his killing spree, he
tried to strangle a young man strangle a young man that he'd brought home.
Police were called to the scene after the man escaped by jumping through
the window. But when the young man and his family declined to press
charges, Nilsen was free to go.
19. December 1978: Nilsen's first kill
Stephen Dean Holmes was 14 when he met Nilsen at a bar in late 1978. The
two went home together, but Holmes never got to leave. Nilsen later said in a
letter written from prison that he killed Holmes because he feared that
Holmes would leave him.
"I had started down the avenue of death and possession of a new kind of
flatmate," Nilsen wrote.
Shortly after, he attempted to kill a student named Andrew Ho, but Ho
escaped and went to the police. However, he declined to formally press
charges, according to the book The Evil Within.
20. December 1979: Nilsen kills Canadian
tourist Kenneth Ockenden
A year after his first murder is when Nilsen killed again, this time a 23-year-
old Canadian visitor to London named Kenneth Ockenden.
21. Early 1980: Martyn Duffey is murdered
The homeless 16-year-old was lured back to Nilsen's apartment with the
promise of shelter and a meal. He became Nilsen's third victim in one of the
murderer's deadliest years. Martyn Duffey's family never stopped searching for
him after he disappeared.
22. Throughout 1980: Several more Nilsen
murders (allegedly)
Nilsen described killing five other people throughout 1980, but only one of
them was ever identified. Scottish-born William "Billy" Sutherland was 26
when he fell victim to Nilsen's crime spree in August of 1980. He was a
boyfriend and father who had gone to London to find work. He reportedly
visited the job center where Nilsen was employed and was killed shortly
thereafter. His family did file a missing persons report for him, but until
Nilsen's arrest, Sutherland's case went unsolved.
It was around this time that Nilsen also allegedly tried to kill 29-year-old
Douglas Stewart, but Stewart overpowered Nilsen and escaped.
23. 1981: Three more unidentified
murders
According to the Evening Standard, Nilsen claimed to have killed “a young
Scot, an English skinhead, and a Belfast boy," none of whom were ever
identified.
24. September 1981: Nilsen kills Malcolm
Barlow
Malcolm Barlow was 24 and homeless when Nilsen reportedly called an
ambulance for him, believing the young man needed a welfare check. Barlow
reportedly sought Nilsen out the next day to say thanks, and instead he was
murdered.
25. November 1981: A would-be victim
escapes
The man who would have been Nilsen's final kill in 1981 actually ended up
escaping. After spending the night with Nilsen, Paul Nobbs, who was 19 at the
time, woke up with a cut on his throat and facial bruises. Nilsen, who
apparently decided to spare Nobbs, suggested he to go to the doctor and let
him leave. Nobbs didn't report the incident to police.
26. March 1982: Nilsen kills John Howlett
Guardsman John Howlett was killed at age 23 after going home with Nilsen.
Howlett reportedly put up a fight, but ultimately Nilsen was able to overcome
him.
27. May 1982: Carl Stotter escapes
After attempting to drown Stotter, Nilsen decided to let him live. Stotter
escaped, he went to the police but they didn't believe his story. He ended up
testifying at Nilsen's trial in 1983.
28. September 1982: Graham Allen is
killed
The 27-year-old Graham Allen was killed by Nilsen in late 1982.
29. Early 1983: Nilsen makes his final kill
and is caught
Stephen Sinclair, who was 20, became Nilsen's final victim in January 1983.
Nilsen disposed of the body by flushing some remains down the toilet, and
eventually the plumbing became stopped up. Nilsen himself wrote a letter of
complaint about the plumbing in February, and a plumber uncovered Nilsen's
terrifying secret. From there, Nilsen was quickly arrested and made a long
confession where he admitted to killing over a dozen people.
30. October 1983: Nilsen gets convicted
and sentenced
Nilsen was convicted of six counts of murder and two counts of attempted
murder. He was initially sentenced to a minimum of 25 years in prison, but
that was later changed to a life sentence. He died while still in prison in 2018
at the age of 72.
32. How he got arrested
On February 4, Nilsen complained to estate agents about the drains being
clogged, seemingly unaware that it was the body parts of his own victims
clogging them.
When plumber Michael Cattran informed Nilsen that he had found the drain
packed with a fleshy substance and small bones, Nilsen joked that someone
was flushing down "their Kentucky Fried Chicken".
Cattran and his supervisor returned the next morning to clear the drain but
found that someone else had done it.
33. Conti…..
Suspicious, they examined the pipes leading to the drain and found more
bones and scraps of flesh in a pipe coming from the top floor of the house,
where Nilsen resided.
After informing police, a pathologist confirmed that the bones were human,
and that one of the flesh scraps was part of a neck bearing marks typical of
ligature strangulation.
As three officers waited for Nilsen to come home, they noticed the smell of
decomposition at his front door.
34. Conti……
Nilsen first feigned shock when the officers told him that the blockage was
caused by human remains, but when they told him to tell them the location
of the rest of the body, he led them to one of the closets containing remains.
When asked if there were more, Nilsen said that it was "a long story" and that
he would tell it all at the police station.
While being driven there, an officer asked Nilsen if the remains belonged to
one person or two.
Nilsen looked out of the window and replied, "Fifteen or sixteen, since 1978."
35. Confession
In an interview conducted on 10 February, Nilsen made a full confession.
Nilsen confessed there were further human remains stowed in a tea chest in
his living room, with other remains inside an upturned drawer in his
bathroom.
The dismembered body parts were the bodies of three men, all of whom he
had killed by strangulation-usually with a necktie.
36. Conti…….
One victim he could not name; another he knew only as "John the Guardsman
"and the third he identified as Stephen Sinclair. He also stated that, beginning
in December 1978, he had killed "twelve or thirteen" men at his former
address, 195 Melrose Avenue. Nilsen also admitted to having unsuccessfully
attempted to kill approximately seven other people, who had either escaped
or, on one occasion, had been at the brink of death but had been revived and
allowed to leave his residence.
37. Conti………
However, he claimed that he had no intention to kill until the moment right
before a murder.
He also claimed that he ignored the reason for the murders, adding that he
hoped the police would tell him. On November 4, 1983, Nilsen was found
guilty of six murders and one attempted murder, and sentenced to life in
prison without parole for 25 years.
The possibility of parole was eliminated in 1994 by Home Secretary Michael
Howard, who replaced Nilsen's sentence with one of whole life order.
Nilsen reacted to the news by saying that he accepted his life sentence and
had no desire to be free again.
