1978-1983

On February 8, 1983, a routine plumbing job in North London uncovered human remains that would lead to one of Britain's most disturbing serial murder cases. The discovery of Dennis Nilsen — and his confessed 15 victims — revealed critical gaps in how European police tracked predatory killers operating within urban anonymity.

Dennis Nilsen, a Scottish-born serial killer, murdered a minimum of 12 young men and boys in London between 1978 and 1983. His crimes went undetected for years until a plumber's discovery in February 1983 led to his arrest and eventual confession to one of Britain's most shocking killing sprees.
