The fatal stabbing of a man who once ran an underground music venue in North Beach has become a murder-suicide after the suspect in the case died at the hospital, according to Police Chief Bill Scott.
Tom Guido, the 58-year-old former manager of the Purple Onion, was stabbed in the neck and head at 908 Post St. on Monday. Police found him dying inside the apartment building after another man jumped out of the third-story window in an attempt to commit suicide, according to the chief.
Both men were taken to the hospital, where Guido died Monday. On Wednesday, police were notified that the man who jumped had also died at the hospital. Though police had not initially determined whether he was a suspect in the case, Scott called him a “suspect” at the Police Commission on Wednesday.
The Medical Examiner’s Office has not released his name as of Thursday.
The killing marked the second homicide of the year in San Francisco and stunned those who knew Guido as the eccentric manager of the Purple Onion in the 1990s. Guido leased the historic comedy club at 140 Columbus Ave. in 1993 and for six years booked underground punk and garage rock bands.
Friends said Guido’s unpredictable antics drew fans to the music venue. He was known for taking over the microphone on stage if a band played too long, or if a toilet was clogged in the bathroom.
In the years since the venue closed in 1999, friends said Guido struggled with mental health issues and often homelessness.
