Welcome Back to "This Day in Scottish History." I'm your host, Colin MacDonald.
Today, we focus on a dark chapter in Scottish criminal history, marking October 24, 1983. On this day, Dennis Nilsen, a man who would become known as one of Scotland's most notorious serial killers, went on trial at the Central Criminal Court in London, accused of six murders and two attempted murders. His story is chilling and complex, one that left an indelible mark not only on his victims' families but on all who followed the grisly details of his crimes.
Dennis Andrew Nilsen was born on November 23, 1945, in Fraserburgh, Aberdeenshire. Raised in a tumultuous household, Nilsen grew up as a quiet child, later joining the Army and serving in various capacities before settling in London. His early life, marked by emotional isolation and unresolved trauma, especially after the death of his grandfather, set the stage for a disturbed adulthood. Nilsen struggled with his sexual identity and developed macabre fantasies that would later manifest in his murders.
Between 1978 and 1983, Nilsen murdered at least 12 young men and boys, all of whom were vulnerable—many were homeless or outcasts from society. He lured them to his home under the guise of friendship, offering them food and alcohol before killing them through strangulation, sometimes in combination with drowning. His methods were methodical, and he would retain the bodies for days, sometimes weeks, engaging in bizarre rituals. Nilsen would bathe and clothe the victims before dismembering their bodies, disposing of the remains in increasingly desperate ways, including burning or flushing parts down the toilet.
Nilsen's crimes were discovered by chance when a plumber investigating blocked drains at Nilsen’s Muswell Hill residence found human remains. On February 8, 1983, Nilsen was arrested after police discovered more body parts in his flat, leading him to calmly confess to the murder of "fifteen or sixteen" victims.
His trial, which began on this day in 1983, was a national sensation. The focus of the prosecution and defense wasn’t whether Nilsen had committed these heinous acts—it was clear from his own confession—but rather his mental state during the killings. The defense argued that Nilsen suffered from diminished responsibility due to mental illness, claiming he was unable to control his violent urges. The prosecution, however, argued that Nilsen was fully aware of his actions and had planned his murders with calculated precision.
Psychiatric evaluations offered differing opinions. One expert described Nilsen as suffering from a personality disorder, marked by emotional detachment and a compulsive need for control over his victims. Another expert refuted this, stating that Nilsen was entirely rational during his killings, motivated by his desire to dominate others and relive the trauma of his grandfather’s death.
After weeks of testimony, the jury found Nilsen guilty of six counts of murder and two counts of attempted murder. He was sentenced to life imprisonment on November 4, 1983, with a recommendation that he serve a minimum of 25 years. In 1994, this was changed to a whole-life tariff, ensuring he would never be released.
Nilsen spent the remainder of his life in prison, where he died in 2018. Even in death, his legacy is one of horror, as he remains a subject of true crime interest and media coverage. His case continues to be analyzed for its psychological and criminological significance, as well as the failures of society to protect his vulnerable victims.
The trial of Dennis Nilsen, beginning on this day in 1983, serves as a grim reminder of the darkness that can exist within individuals and the lasting impact such crimes can have on communities and families.
