Police say they have arrested a 47-year-old man suspected of slaying three of his former co-workers at a Silicon Valley high-tech firm.
Santa Clara Police Lt. Mike Sellers says Jing Hua Wu was arrested without incident in Mountain View on Saturday.
Wu had been missing since the Friday afternoon shootings at the offices of SiPort Inc., a company that develops digital radio semiconductors.
Police say Wu had been let go this week from his job as a product test engineer.
Police identified the victims as Sid Agrawal, SiPort's chief executive officer: Brian Pugh, the company's vice president of operations and Marilyn Lewis.
Wu is being booked into Santa Clara County Jail, where he will be held on three murder counts.
