The beginning of the end for Sid started on October 12, 1978, when girlfriend Nancy Spungeon was mysteriously found dead from a stab wound in room 100 of the Chelsea Hotel.
Over the next three months, Sid was arrested for Nancy’s murder, set free on bail, and sent to Bellevue after slashing his wrists in a suicide attempt.
After his Bellevue stint, he was then shipped back to Rikers Island for slashing Patti Smith’s brother’s face with a bottle at a club.
Released from Rikers on February 1, 1979, he headed over to 63 Bank Street (right), where his new girlfriend had an apartment.
During a party that night celebrating his release, Sid shot up heroin several times. (Reportedly, he got the heroin from his own mother.)
He was found dead there in the morning.
