Santa Clara police arrested a laid off technology company employee Saturday who returned to the business Friday afternoon and fatally shot three employees.
Mountain View resident Jing Hua Wu, 47, was an engineer at SiPORT Inc., which makes chips for high-definition radios, Santa Clara police Lt. Mike Sellers said.
Wu was laid off Thursday or Friday and returned to the business at 3255 Scott Blvd., Building 7, Suite 102, just before 4 p.m. Friday, Sellers said.
Wu was inside the business when he opened fire, killing SiPort CEO Sid Agrawal, 56, of Fremont; Vice President of Operations Brian Pugh, 47, of Los Altos; and Head of Human Relations Marilyn Lewis, 67, of San Jose, Sellers said.
Police believe Wu used a handgun to kill the three victims.
Officers were called to the business on reports of multiple gunshots and found the three victims suffering from fatal gunshot wounds.
Witnesses were able to quickly identify Wu as the shooter, police said.
Wu allegedly fled the building before police arrived. He was seen driving away from the building in a silver Mercury Mariner sport utility vehicle, Sellers said. Police discovered the SUV had been rented.
Officers searched the area when they arrived but were unable to locate Wu, who was considered armed and "extremely" dangerous, Sellers said.
The description of Wu and his rental vehicle was broadcast statewide, and officers investigated Wu's Mountain View home.
After extensive searches, officers located Wu around 10:45 a.m. Saturday.
Wu was found in the area of El Camino Real and Grant Road in Mountain View and arrested without incident, police said.
He has been booked into the Santa Clara County Jail on suspicion of three counts of homicide.
Sellers said the motive in the shooting is unknown.
"He was recently let go from the company, so that is a possible motive," Sellers said.
SiPort's Web site states that the company was incorporated in 2004 and received its first round of funding in 2005. Additional information from the Web site was unavailable, as links to information about management and investors were down this afternoon.
An investigation into the shooting is ongoing, and anyone with information is asked to contact police at (408) 615-4800.
