UMATILLA COUNTY, Ore. — A rollover crash on Interstate 84 in Umatilla County sent four people to the hospital Thursday morning, including three passengers who were later transferred for advanced medical care, according to Oregon State Police.

OSP said troopers responded at 8:27 a.m. Thursday, July 16, to a single-vehicle serious injury crash on I-84 eastbound near milepost 207.

Investigators said a gray Dodge Durango driven by Cullen Michael Derr, 38, of Battle Ground, Wash., was eastbound while towing a custom-built utility trailer when, for an unknown reason, it left the roadway. The vehicle rolled multiple times and caught fire, OSP said.

Police said three occupants were ejected during the crash: a 24-year-old woman, a 15-year-old male and a 9-month-old male infant. OSP said all four occupants, including Derr, were taken to a local hospital, and the three passengers were later transferred to hospitals in Oregon and Washington because of the severity of their injuries.

Derr was arrested for DUII, reckless driving, reckless endangering another person (three counts) and third-degree assault (three counts), and was lodged at the Umatilla County Jail, OSP said.

Interstate 84 was impacted for about one hour during the on-scene investigation. OSP said it was assisted by the Pendleton Police Department, Pendleton Fire & Ambulance Department, and the Oregon Department of Transportation.
