A gunman fired a bullet into his own head after killing three people at a UPS facility in San Francisco on Wednesday.
Assistant Police Chief Toney Chaplin told reporters that the two other people who were shot in the attack, have survived. When confronted by the police, the gunman then fatally shot himself, reports CNN.
Police responded to a report of an active shooter at the UPS San Francisco Customer Center, following which officers arrived and found out that the suspect was still inside the building.
A police "contact team" soon found the gunman armed with an assault pistol, the assistant chief said.
"The suspect put the gun to his head and immediately discharged the weapon," he said.
UPS spokesman Steve Gaut released a statement saying that six employees were involved in a "shooting incident" but that the company cannot provide any identifications until the police investigation is complete.
Although the suspect was wearing a UPS uniform, investigators have yet to confirm he was an employee.
So far, there is no evidence to suggest that the shooting was terror-related.
