The October 1978 slaying of Nancy Spungen, the Huntingdon Valley-raised punk-scenester, is the topic of an upcoming documentary. "Who Killed Nancy?" by Alan G. Parker, due out early next year, explores the possibility that Spungen was killed by someone other than boyfriend Sex Pistols bassist Sid Vicious, who was charged in her death but was never tried, because he OD'd on heroin only months later. Spungen was 20-years-old when she bled to death after a stab wound to the abdomen in the bathroom of a room she and Vicious shared at New York's Chelsea Hotel, is buried at King David Cemetery, in Bensalem. A New York mag story by Karen Schoemer this week details the tragic tale of Spungen, who was a drug dealer and prostitute.
