"Four people have died, including the suspect, and at least seven more were injured in a shooting involving UPS employees at the company’s facility in the Potrero Hill neighborhood Wednesday morning.
The shooter is believed to be a UPS employee who police said turned the gun on himself after officers responded to the scene. A source with knowledge of the investigation confirmed the shooter has been identified as Jimmy Lam, and the Examiner witnessed a BMW recovered at the scene by police, which sources said was registered to Lam.
Assistant Chief Toney Chaplin, however, would not identify the shooter at a news conference Wednesday afternoon.
Late Wednesday night, however, police released the name and age of the suspect.
Jimmy Lam, 38, of San Francisco, was identified as the deceased suspect by the Medical Examiner’s Office, Sgt. Michael Andraychak said in an email.
The shooting was reported around 9 a.m. at the packaging and sorting facility at 320 San Bruno Ave.
Chaplin told reporters at the scene that three victims were killed in the shooting before the suspect turned the gun on himself. Seven other victims were injured, some of whom were injured while fleeing the scene.
Officers in a later sweep of the UPS facility found one injured victim who was hiding, Chaplin said.
The suspect was dressed in a UPS uniform, but authorities have not confirmed whether he was an employee at UPS.
“We do not believe this incident is related to terrorism,” Chaplin said.
While the victims have also not been identified by authorities, Mike Lefiti, a UPS employee, has been identified by multiple news outlets and on his personal Facebook as one of the victims.
“He was my big brother,” wrote Rock Asis on Facebook. Lefiti “always give me ride to skool [sic] and take me everywhere … thank you for everything u [sic] have done for me as I was growing up.”" (
