An allegedly intoxicated woman driving on U.S. Highway 97 struck and injured a pedestrian Thursday at the Huntington Road intersection in La Pine, according to the Deschutes County Sheriff’s Office.

Sheri Lynn Barnes, 53, La Pine, was driving a red 2012 Kia Rio southbound on the highway at about 10:15 a.m. when she allegedly hit 77-year-old Harold Headrick, of La Pine, who was walking west to east across the highway, according to the sheriff’s office, which had received reports that Barnes was driving erratically.

Barnes stopped after the crash and remained at the scene. The sheriff’s office says she was under the influence of a controlled substance at the time of the crash.

She was arrested on charges of second-degree assault, unlawful possession of methamphetamine, driving under the influence of intoxicants, reckless driving and reckless endangering.

Headrick was transported to St. Charles Bend with life threatening injuries.

Traffic on U.S. Highway 97 was detoured around the crash scene while deputies completed their investigation.

The sheriff’s office was assisted by the Oregon State Police, Oregon Department of Transportation, and La Pine Fire Department.
