Sid Vicious was a punk rock icon, former bassist in the Sex Pistols, a heroin addict, and a suspected murderer. In 1978, his girlfriend, 20-year-old Nancy Spungen, was found murdered on the bathroom floor of the Chelsea Hotel room they shared in New York City. Less than four months later, Sid died of a fatal heroin overdose. His death came as a surprise to very few people. Sid infamously once said, “I’ll die before I’m 25, and when I do I’ll have the lived the way I wanted to.” This is the tragic timeline of his misfortunate life and doomed 19-month relationship with Nancy.
