San Francisco's nastiest serial killer, Richard Ramirez, nicknamed "The Night Stalker" stayed in Room 315 of the Bristol Hotel (pictured) in the Tenderloin district. The story has resurfaced in Tenderloin, which recalls how he was captured when one of the staff recognised him from a police sketch. Ramirez murdered people in their beds and left satanic symbols daubed on their walls. A pentagram was painted on the bathroom door of Room 315 and police took it away. In the same hotel at this time was Valerie Solanas, would-be assassin of Andy Warhol, whose story is told in "LL Cool J and the Woman who Shot Andy Warhol", chapter 7 in High Times at the Hotel Bristol - now available as an eBook.
Solanas died in the hotel, aged 52, in 1988. Ramirez is on Death Row in San Quentin prison, awaiting execution.
