One dead, another injured in shooting onboard Muni bus

San Francisco police are investigating a deadly shooting that happened on a Muni bus in the Sunnydale neighborhood on Wednesday afternoon.

Officers said they responded to reports of the shooting on a no. 8 Bayshore bus that was bound for Fisherman's Wharf. Officers arrived in the area of Velasco Avenue and Santos Street at around 3:20 p.m. where they found two victims, one with life-threatening injuries and another with non-life-threatening injuries. 

The victim with life-threatening injuries was transported to a nearby hospital where they later died. The second victim is expected to recover.

It remains unclear what led up to the deadly shooting and whether the shots were fired between the two victims or another unidentified person.

At this time, no suspects have been arrested. It is not clear if this was a targeted shooting. Police said they are looking at potential witnesses, including those who were riding the bus at the time of the shooting as well as the Muni operator. 

Muni vehicles are equipped with security cameras. Police will review that footage in hopes of determining who is responsible for this shooting. 

Officials asked the public to avoid the area as the investigation is ongoing. By 7 p.m., the scene was cleared. 

A fatal shooting happened on a Muni metro light-rail vehicle earlier this summer. A defense attorney for the accused gunman said the shooter, a security guard, acted in self-defense.

Police are asking anyone with information on Wednesday's shooting to call the SFPD Tip Line at 1-415-575-4444.
