Man who killed a police officer during a bondage sex session and then attempted to cook and eat his body parts has been jailed for life by a judge in London.

Judge Nicholas Hilliard sentenced Stefano Brizzi on Monday to life in prison with at least 24 years to serve for killing 59-year-old Gordon Semple, whose dissolving body was found in an acid bath, according to ABCnews.

Brizzi, a former Morgan Stanley IT developer, met Semple on a gay dating app. The 50-year-old Brizzi arranged a meeting at his apartment near London’s Tate Modern gallery on April 1 and later tried to cover up his tracks online.

After his arrest, Brizzi had admitted killing and trying to dissolve the body because “Satan told me to.”
