California Highway Patrol reports indicate the accident occurred at 5:10 p.m. Friday afternoon. John Greaves, 44, of Walnut Creek was riding south on Camino Tassajara when he was struck from behind by a Honda Civic. CHP officers said the driver apparently lost control of the vehicle and struck the cyclist, then swerved into the northbound lanes of traffic and struck an oncoming vehicle.
Greaves and his bicycle were rolled under the Honda as it collided with the second vehicle, a Range Rover. Police and fire officials converged on the scene, where Greaves was pronounced dead from his injuries. The driver of the Honda, identified as Hong Guo, 40, of Cupertino was injured in the crash and taken to John Muir Medical Center in Walnut Creek. The driver of the Range Rover, a 30-year-old Danville man, was not injured.
The crash occurred on a narrow, winding stretch of Camino Tassajara that has no shoulder and no bike lane. That area has become much more heavily traveled by automobiles as drivers use Camino Tassajara as a bypass to the congested I-580 and I-680.
CHP Officer Steve Creel said police are looking to speak to the driver of a light-colored, medium-sized SUV which may have witnessed the crash. Creel said the driver, described as a male, was reportedly close behind the vehicles involved in the incident but left before CHP arrived. Police said they are hopeful the driver may be able to help determine the cause of the crash.
"What we're going to do over the next week is talk to all of the people involved in the accident, and then the witnesses. Then we'll go back over it with them," Creel explained.
Initial reports indicated that police did not suspect drugs or alcohol as a cause in the accident. Creel said their investigation has not found any evidence to the contrary so far. "We have seen nothing to make us think there was any drugs or alcohol involved," he stated.
Greaves was a senior vice president and branch manager for Morgan Stanley Smith Barney in Walnut Creek. A cycling enthusiast currently in training for the upcoming Vineman Triathalon, he is survived by his wife and two children.
Any person with information regarding the crash is asked to call the Dublin CHP office at 828-0466.
