Multnomah County Sheriff’s Office Seeks Help Identifying Semi-Truck Involved In Hit-and-Run Rollover Crash - 05/20/26
MULTNOMAH COUNTY, Ore. – The Multnomah County Sheriff’s Office is releasing video that captured a rollover crash to help with a hit-and-run investigation.
This investigation began around 9 p.m. on Monday, May 18, 2026, when deputies with the Multnomah County Sheriff’s Office responded to a crash that occurred about a half mile west of Dalton Point Recreation Site on eastbound I-84.
Based on the preliminary investigation, the driver of a blue or purple-colored semi-truck pulling a trailer initiated a lane change into the path of a white-colored commercial water truck. The driver of the water truck lost control when the semi clipped its front passenger side, causing the water truck to swerve off I-84, travel roughly 100 feet into a thickly wooded area, and roll onto its driver’s side.
Neither the driver nor passenger in the water truck suffered serious injuries. The driver is cooperating with the investigation.
The semi-truck driver did not stop. The Multnomah County Sheriff’s Office needs assistance locating and identifying the driver of the semi-truck and its owner.
Due to the truck's position upon crashing – intertwined with brush and trees – firefighters evaluated the scene and confirmed the tank contained only water, ruling out a hazardous materials threat.
Deputies requested the assistance of a local tow company to complete a complex recovery. The process utilized two heavy-lift vehicles to remove the severely damaged water truck.
Anyone with information about the semi-truck involved in this crash is asked to call 503-988-0560 or email tips@mcso.us.
