A 30-year-old Chino Hills man died Wednesday after he was thrown from his motorcycle on the 60 Freeway in South El Monte, then struck by a big rig which continued driving, authorities said.
Troy Dean Olson died in the crash, which took place shortly after 6:30 p.m. in the eastbound lanes of the freeway, just east of Cogswell Road, Los Angeles County Department of Coroner Lt. Fred Corral said.
Olson was driving a 2013 Honda motorcycle at an unknown speed in the No. 3 lane prior to the crash, Officer M. Gonzales of the California Highway Patrol’s East Los Angeles office said. The motorcyclist applied his brakes due to slowing traffic ahead.
“(Olson) lost control of the motorcycle, causing him to be ejected onto the No. 4 lane,” Gonzales said. A passing big rig then ran over the rider.
Paramedics pronounced Olson dead at the scene, officials said.
Witnesses on-scene stated the driver of the tractor-trailer momentarily stopped and then proceeded to drive away from the scene of the collisions,” Gonzales said.
A description of the driver was not available, however the big rig was described as a dark-colored tractor with a gray or white trailer, he said.
Anyone with information was asked to contact the East Los Angeles office of the CHP at 323-980-4600.
