Sex Pistols bassist Sid Vicious had been taken in two months before for allegedly murdering his girlfriend, Nancy Spungen, but while out on bail he was arrested again in December 1978 after bottling singer Patti Smith's brother Todd during a Skafish concert. After spending two months on Rikers Island, he died of a drug overdose the very same day he was released. Or was it a suicide? A recent film suggests a note found on Vicious at the time of his death revealed Spungen may have died as part of a suicide pact gone wrong -- and Sid's death was his end of the bargain.
