SAN JOSE -- A man committed suicide after leading police on a high-speed chase on northbound Highway 101 and striking another car Monday night, authorities said.
The driver of the other car was not seriously injured.
Santa Clara Sheriff's deputies were first notified by the man's son that something was wrong when the son approached officers near the massive Curie Drive fire around 3:30 p.m., said Santa Clara County Sheriff's Sgt. Kurtis Stenderup.
The son told deputies his father had left a suicide note and that he was going to harm himself somewhere in Santa Teresa County Park, Stenderup said, and deputies immediately began their search. A short time later, deputies found the family dog shot dead in the park, but the man was nowhere to be found.
Around 6 p.m., Stenderup said deputies found the man's white Toyota Avalon at the park. As they were setting up a perimeter to try and determine if anyone was inside, the man turned on the car and sped out of the park, driving erratically as he went.
Deputies jumped in their cars and followed the man, who drove onto northbound Highway 101 and at times reached speeds of over 100 mph, Stenderup said.
The deputies lost the car, and drove farther up the highway. The man took the Tully Road offramp, where he rammed the back of a gray SUV, causing it to flip. The SUV driver suffered bruises on his head and declined medical transport.
The man's Toyota slammed down a small, grassy embankment before coming to a stop on the Highway 101 onramp at Tully Road.
A sheriff's deputy, driving back from training, saw the aftermath of the collision and immediately drove down to try and help, Stenderup said. As the deputy parked his patrol car, the driver of the Toyota jumped out of his car and shot himself in the head.
The man was not immediately identified. Both the Highway 101 offramp and onramp at Tully Road were closed while crews investigate.
