Who Killed Nancy? Did Anyone Bother Asking Stanley?

According to this new documentary, Who Killed Nancy? by Alan G. Parker, neither Sid Vicious nor Rockets Redglare was the killer of the nauseating one.  Instead, Parker fingers a shadowy blond-haired Brit from the 6^th floor of the Chelsea Hotel, known only as “Michael.”  Who is this Michael, and what has become of him?  He could still be living on the 6^th floor, for all we know!  Only Stanley Bard knows for sure.  Bring Back the Bards!
