Police were searching Saturday for a disgruntled engineer who allegedly gunned down three people at his former office building in Santa Clara a day earlier.

The suspect was identified as 47-year-old Jing Wu of Mountain View, who police say had been let go from semiconductor company SiPort Inc.

Two of the victims were identified as Sid Agrawal, SiPort chief executive officer, and Brian Pugh, the company's vice president of operations. A woman was also killed in the Friday afternoon shooting.

Police stopped cars and scoured the office park where SiPort is located. They also went to Wu's Mountain View home, Santa Clara Police Lt. Mike Sellers.

Sellers described Wu as about 5 feet 11 inches tall and weighing 170 pounds. Investigators believe he fled the complex in a silver Mercury Mariner SUV.

"He could be anywhere," Sellers said. "He's considered armed and dangerous. If you see him, don't approach him, call the police."
