In mid-June, at a UPS customer center in the South of Market district in San Francisco, UPS employee Jimmy Lam, 38, opened fire on his colleagues, killing three people and injuring two others. San Francisco police responded to an 8:55 a.m. report of an active shooter. As they entered the building, Lam killed himself.
