Four killed at San Francisco UPS depot before driver shoots himself

A UPS driver shot and killed three people at a UPS facility in San Francisco yesterday, before turning the gun on himself. The shooter, identified by the LA Times as a Jimmy Lam, had reportedly filed grievances over excessive overtime with his local Teamsters Union representative in March. A spokesperson for UPS told the paper Mr Lam was wearing his uniform when he opened fire inside the four-story shipping facility. At the time, workers were gathering for their morning meeting before departing to deliver parcels. Two more employees were hit by gunfire, while five sustained injuries believed to have occurred during the rush to escape the incident.
