SUNRIVER, OR -- An 84-year-old Terrebonne man died in a crash near Sunriver, Wednesday morning. Investigators believe Gary Lawrence may have suffered a medical problem, causing him to run off the road.

Witnesses say his pickup suddenly accelerated on South Century Drive, missed a curve and went down an embankment into a group of trees. The pickup rolled onto its top and, when emergency crews arrived, Lawrence was found deceased.

The Sheriff’s Office says weather and road conditions did not appear to be factors.
