Keizer Woman Passes After Single-Vehicle Crash on Highway 31 in Lake County
In Lake County, Oregon, at approximately 6:32 a.m. on Thursday, November 6, 2025, tragedy struck when Sydney-Marie Kathrine Dobson, 33, of Keizer, lost her life in a single-vehicle crash along Highway 31 near milepost 71.
According to reports from the Oregon State Police, Sydney-Marie was traveling northbound in her Honda Accord when she failed to navigate a curve. The car left the roadway and rolled before coming to a rest off the shoulder. Authorities determined that she was not wearing a seatbelt at the time of the crash, and she was ejected from the vehicle. Despite immediate response from emergency personnel, Sydney-Marie was pronounced deceased at the scene.
The Scene of the Accident
The crash occurred on a rural stretch of Oregon Route 31, a highway known for its long, winding roads through open landscapes in central Oregon. The area near milepost 71 is often quiet and sparsely traveled, particularly in the early morning hours when this accident took place. Weather conditions that morning were reported as cool and dry, though the precise cause of the crash remains under investigation.
Responding officers from the Oregon State Police and Lake County emergency services arrived quickly, closing a section of the highway to conduct a detailed investigation. Members of the Oregon Department of Transportation also assisted at the scene, managing traffic and clearing debris as the Major Crash Team began reconstruction efforts.
Investigators are expected to review factors such as vehicle speed, tire condition, road surface, and possible distraction or fatigue. Toxicology tests will also be performed as part of standard procedure, though no suspicion of impairment has been reported.
