Dennis Andrew Nilsen was a Scottish serial killer and necrophile who murdered at least twelve young men and boys between 1978 and 1983 in London. 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, with a recommendation that he serve a minimum of 25 years. This recommendation was later changed to a whole life tariff in December 1994. In his later years, Nilsen was imprisoned at Full Sutton maximum security prison.
