Campbell appeared Monday in Clark County Superior Court to face a vehicular assault allegation stemming from a Saturday crash that injured six people.The 23-year-old Vancouver resident was arrested following the crash at 1:58 a.m. in the 24400 block of Northeast Rawson Road, near Northeast Hinness Road in the Proebstel area east of Hockinson, according to the Clark County Sheriff’s Office. Alcohol is believed to be a contributing factor in the crash.Judge Gregory Gonzales set Campbell’s bail at $15,000.An investigation determined that Campbell was driving a 1998 Chevrolet full-sized pickup west on Rawson Road when he allowed the vehicle to drift off the road. Campbell brought the pickup back onto the pavement, but crossed the center line into oncoming traffic.The pickup crashed head-on into an eastbound 1998 Nissan Sentra, injuring three in the car, one seriously, before rolling onto its passenger’s side into the path of a westbound 1999 Ford pickup, the sheriff’s office said. Three passengers in Campbell’s Chevrolet were also injured. Their names were not released.According to a probable cause affidavit, the driver of the Nissan was extricated from his vehicle and taken to PeaceHealth Southwest Medical Center in Vancouver. When a deputy later checked on the driver, he was told the man had suffered broken bones in his arms, hands and face.
