ONTARIO (CBSLA.com) — An on-duty police officer was killed Thursday during a traffic collision that occurred in Ontario.

“Unfortunately during the collision the officer did receive fatal injuries,” said Det. Bill Russell. “He was transported to a hospital where he later died.”

Authorities identified the victim as Bryce Hanes, 40, of Redlands. Hanes was a 12-year veteran of the San Bernardino Police Department.

A preliminary investigation revealed the officer had just dropped an inmate off at the West Valley Detention Center and was broadsided by a 2008 Dodge Charger. The cause of the crash forced the police cruiser to then collide with a pole.

Detective said the 27-year-old Fontana driver of the Dodge, Archie Green, reportedly ran a red light at the intersection. He is being evaluated and will be booked on suspicion of a felony charge for driving under the influence and vehicular manslaughter.

At this time, it remains unclear if speeding played a factor in the crash.

Meanwhile, police have expressed their condolences to the Hanes family on Twitter.

Gov. Jerry Brown ordered capitol flags to be flown at half-staff in honor of Hanes.

“We offer our heartfelt condolences to Officer Hanes’ family, friends and coworkers at the San Bernardino Police Department,” Brown said in a statement. “we join all Californians in mourning his loss and vow to always remember his selfless service and sacrifice on behalf of his community.”

Hanes leaves behind a wife, two daughters and a son.

“It’s always tragic when children lose their parents, so we are feeling very sad for them. They’re in our prayers for sure,” neighbor Lori Bruch said.
