Dennis Nilsen – The Kindly Killer | The MONSTER Next Door

Dennis Nilsen, one of Britain’s most notorious serial killers, preyed upon young men in London between 1978 and 1983. Often called The Kindly Killer for his deceptive, almost gentle approach, Nilsen lured vulnerable men into his home, where he would murder them and keep their bodies for days — sometimes weeks.Over a five-year killing spree, Nilsen claimed at least 15 victims, though the true number remains uncertain. His crimes went undetected for years, in part because his victims were often overlooked by society — young men experiencing homelessness, isolation, or estrangement from their families.In this full true crime documentary, we explore the disturbing life of Dennis Nilsen — from his troubled childhood and military service to his horrific murders, trial, and eventual death in prison. We also examine the investigative failures that allowed him to keep killing, and the lingering questions that remain to this day.This is the story of a man who lived with the dead… and the lives he destroyed.☕ Support the channel: https://buymeacoffee.com/horrorlocker
