A gunman opened fire at a UPS facility in San Francisco on Wednesday morning, killing three people and later dying of a self-inflicted wound, police say. The shooting, which unfolded on the eastern edge of the city's Mission District, began at around 9 a.m. local time, just as the workday was getting underway.
Authorities said the gunman was wearing a UPS uniform. Company spokesman Kyle Peterson tells NPR that the shooter was a current UPS employee.
Two other employees were injured in the shooting, Peterson says.
