Memories of a Murderer: The Nilsen Tapes begins at the end — with serial killer Dennis Nilsen getting arrested and confessing to murdering 15-16 young men. He would ultimately be convicted of only six murders. Over the course of the Netflix documentary, Nilsen's own audio tapes are played as he claims he had difficult childhood and adulthood that eventually took a turn towards murder. But the movie hops around throughout the ‘70s and ‘80s, which doesn't present the clearest timeline of Dennis Nilsen’s crimes.

For five years, Nilsen was able to get away with killing multiple young men, in part, because he targeted homeless youths, drifters, sex workers, and gay men. The ex-cop took advantage of London's then homophobic culture, which also made it difficult for the several survivors of Nilsen’s to come forward or to be believed if and when they did.

Late '70s: Nilsen's first would-be victims escape

According to investigators interviewed in the film, before Nilsen had formally started his killing spree, he tried to 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. It was around this time as well that Nilsen met Martyn, who declined to share his last name in the documentary. According to Martyn, Nilsen also tried to kill him after they went back to his apartment, but Martyn managed to escape. He said he didn't go to the police at the time because he feared he'd be met with homophobia.

December 1978: Nilsen's first kill

According to the Daily Star, 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. The Star reported that 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.

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.
