UPS employee kills three coworkers in San Francisco

UPDATE: The UPS employee who shot and killed three co-workers Wednesday in San Francisco had filed a grievance for excessive overtime. Joseph Cilla, an official with a Teamsters Union local that represents UPS workers, said 38-year-old Jimmy Lam filed the grievance in March. Lam complained of too much overtime and requested UPS relieve him from working extra hours. Assistant Police Chief Toney Chaplin said security officials have yet to confirm the motive for the shooting. Lam walked in during a morning meeting and shot three people: 50-year-old Benson Louie, 56-year-old Wayne Chan, and 46-year-old Mike Lefiti.
