The person killed over the weekend at a microprocessor manufacturing facility in suburban Phoenix was a 49-year-old man who worked at the plant, authorities said Monday.

Chandler police identified the victim as Dan Foster, an employee of the Intel plant. Court documents say he was found dead in the cafeteria of Intel's Ocotillo Campus with blunt-force trauma from a baseball bat. A hatchet and knife were also found at the scene.

Fellow worker Jaron Williams, 27, was also hurt in the attack and hospitalized with injuries that were not life-threatening.
