1 killed in multi-vehicle accident that snarls traffic on I-10 in Upland


A fatal accident Sunday night involving at least half a dozen vehicles nearly shut down both sides of Interstate 10 in Upland as emergency responders tended to the injured and authorities investigated what happened.

One person died at the scene and another person with life-threatening injuries had to be extricated from a badly damaged vehicle, said Chris Gorman, incident commander for the San Bernardino County Fire Department. That individual and two others with lesser injuries were taken to the trauma unit at Pomona Valley Hospital Medical Center.

Other people with potential injuries were treated or interviewed at the scene and declined to be taken to the hospital.


Initial reports indicated as many as 10 vehicles were involved in the accident, but some of those might have had minor damage or belonged to witnesses or those who stopped to help, Gorman said. Five or six vehicles had occupants with potential injuries.

The person who died was driving alone. Further information about that individual was not immediately available.

San Bernarndino County sheriff’s deputies responded to an overnight call to find a 7-month-old not breathing. Investigators said they found signs of abuse.

The accident first appeared in the official California Highway Patrol log shortly after 8 p.m. The entry at 8:08 p.m. reported all lanes stopped, without further detail. The incident commander said the freeway wasn’t completely closed, but traffic was significantly backed up as only a single lane was open in each direction for an extended period.

The coroner was called at 9:19 p.m. and a SigAlert — documenting a major closure — was issued at 9:32 p.m.

Shortly before 10 p.m., the Fire Department said the injured had been taken for treatment and the scene turned over to the highway patrol for further investigation.

By 10:05 p.m. all the westbound lanes had reopened.
