SAN JOSE -- Police have identified the man who was fatally shot by two veteran officers after leading police on a high-speed pursuit Saturday as 28-year-old Ronald Aduddell of San Jose.

Police say Aduddell pointed a gun multiple times at officers during a 30-minute pursuit which began near Union and Bascom avenues and ended in South San Jose. Police have not yet located a gun.

When the chase was over, Aduddell quickly got out of his car with his hands near his waistband, according to Sgt. Jason Dwyer. Officers Ian Cooley, a 16-year police veteran, and Adam Jenkins, a 13-year veteran, believed Aduddell was reaching for a gun and opened fire.

"Everything happened very quickly," Dwyer said. "They're believing he's reaching for the gun they heard about on the radio . So they fired at the suspect, believing they are about to be fired upon."

The pursuit began Saturday at about 2:35 p.m. when an officer on routine patrol in West San Jose saw a man in a tan Ford Contour acting suspiciously in the area of Union and Bascom avenues, Dwyer said.

When the officer approached the Contour, it took off.

"The officer believed he was acting suspiciously," Dwyer said. "That could have been anything from getting ready to commit a vehicle burglary or residential burglary, and that is precisely what we're trying to prevent these days, with our crime levels the way they are. This officer was out doing good proactive police work."

The officer did not chase the Contour but instead drove around the area and located the car a short time later. Police say Aduddell rammed the marked black-and-white patrol car head-on.

The officer broadcast that he had been assaulted and more officers quickly joined in the pursuit.

"Multiple times during the radio tapes, you can hear officers say he's pointing a gun at us right now," Dwyer said. "They're fearful they're going to be shot at at any moment."

A number of items were thrown out of the Contour, including a purse and other items that did not belong to Aduddell. Police say the license plates on the suspect vehicle were stolen.

Aduddell eventually merged onto southbound Highway 85 from Bascom. Police say Aduddell tried to drive the wrong way against traffic, but the first officer who spotted him blocked the path of the Contour, causing a collision.

Police finally boxed the Contour in at Blossom and Calero avenues, Dwyer said. By then, the Contour was moving very slowly, having been damaged in the collisions with police.

Police shut down a portion of southbound Highway 85 on Sunday to search for the gun.

"We did a methodical search on 85 looking for the gun," Dwyer said. "And we've tried to search as much of the pursuit route as possible. We haven't found one."

Police are asking anyone why finds a gun between the areas of Bascom and Union avenues and South San Jose to contact them.
