The California Highway Patrol said a man from Clayton, California, was the person killed after riding his skateboard under a moving dump truck on Glendora Mountain Road around 9:40 a.m. Friday.
The 20-year-old man had been riding on the road with friends south of East Fork Road at about 20 to 30 miles per hour northbound on a downhill curve he attempted to maintain. The victim failed to remain in his lane and crossed the double yellow lines, said Rodrigo Jimenez, public information officer with the California Highway Patrol.
The truck driver, a 45-year-old man from Compton, was driving a three-axle dump truck uphill at about 15 to 20 miles per hour. The victim rode head on into the dump truck and was subsequently struck and became pinned underneath, Jimenez said.
The victim suffered blunt force trauma. Fire fighters with the U.S. Forest Service attempted aid, but the man was declared deceased by Los Angeles County Fire Fighters soon after.
According to a witness at the scene, the victim had been riding on Glendora Mountain Road while possibly three friends were trailing him in a vehicle. The victim was wearing a helmet.
Glendora Mountain Road at East Fork Road had been closed in both directions most of the day but was reopened at 2 p.m., Jimenez said.
The victim’s name has not been released, pending notification of next of kin.
