SAN FRANCISCO (AP) – Jimmy Lam had his troubles: a drunk driving conviction, a grievance against his company, a struggle with personal issues and depression a few years ago.
But colleagues and investigators say none of it helps explain why the UPS driver showed up at his San Francisco workplace and gunned down three colleagues, wounding two others.
Lam, an 18-year veteran of UPS, appeared to single out the three slain drivers but investigators have yet to determine a motive for Wednesday’s attack, an official in the San Francisco Police Department said.
The official was not authorized to discuss the case publicly and spoke on the condition of anonymity.
The violence ended when the 38-year-old Lam turned the gun on himself and took his own life as workers ran from the packing facility and police closed in.
