Born John Simon Ritchie, Sid Vicious was an English punk rock musician who played bass for the Sex Pistols. After the band broke up in 1978, he embarked on a solo career, with his girlfriend, Nancy Spungen, acting as his manager. The two—heroin addicts—quickly spun out of control.

Did he kill her? Discuss
