Manhunt nets murder suspect

An engineer who police said fatally shot three former co-workers at a Silicon Valley high-tech company was arrested after a daylong manhunt.

Jing Hua Wu had been missing since the shootings on Saturday at the offices of SiPort, a four-year-old company that develops digital radio semiconductors.

Police said Wu had been let go this week from his job as a product test engineer and that he appeared to have specifically targeted his three victims, who were executives of SiPort.
