Umatilla County, OR – A pedestrian, identified as 31-year-old Breann Hailey Mayberry of Umatilla, was struck and killed in a hit-and-run collision involving a commercial motor vehicle on Highway 395 early Monday morning, according to the Oregon State Police.
The incident occurred at approximately 5:53 a.m. on December 1, 2025, on Highway 395 near milepost 2, where authorities located the victim on the northbound shoulder. Evidence at the scene suggested involvement of a white commercial vehicle.
According to investigators, the involved vehicle was traveling along Highway 395 and was later identified as a white Freightliner commercial motor vehicle with a trailer.

He was arrested on suspicion of Failing to Perform the Duties of a Driver. Brown was reportedly uninjured in the incident.
First responders confirmed that Mayberry died at the scene. Oregon State Police were assisted by the Hermiston Police Department, Umatilla County Fire District 1, and ODOT during the response and investigation. Authorities closed portions of Highway 395 for roughly five hours while documenting evidence and securing the vehicle involved. The investigation remains active.
The exact cause of the collision has not yet been determined, and investigators continue to review physical evidence and witness information to establish how the events unfolded. Additional details may be released as the investigation progresses.
