SOLANA BEACH - The motorcyclist killed in a two-vehicle crash near the Del Mar Fairgrounds over the weekend was identified today as a 22-year-old Escondido man.
Alexander Mackenzie Williams was headed west on Via de la Valle near Jimmy Durante Boulevard at a high rate of speed shortly before 6:30 p.m. Sunday when he lost control and swerved into oncoming traffic, according to the San Diego Medical Examiner's Office and the San Diego County Sheriff's Department.
“The motorcycle kept going but his body just stopped,” witness Elizabeth Gilroy told 10News. “So I looked at him and said, ‘we have to do something.’ And people were running towards the body and people were yelling ‘don’t touch him, he's not moving, he's not breathing.’”
Sheriff's officials said it is possible that Williams had been riding in tandem with another rider or racing another rider just before the crash. He could have struck a cone being used for traffic control near the Del Mar Racetrack, they added.
Williams was thrown from the motorcycle and landed under the front end of a stopped Hyundai, sheriff's Sgt. Joe Tomaiko said. Williams' motorcycle then crashed into an eastbound Toyota sedan, then two other vehicles.
Williams died at the scene, authorities said.
Tomaiko said none of the other vehicles' occupants were injured and that alcohol was not believed to have been a factor in the crash.
