A single-vehicle collision in northwestern Dawson County claimed the life of a Dade County man two days before Christmas. Dawson County Coroner Ted Bearden said Sai Hwan Oh, 72, of Trenton, died from injuries sustained in the Dec. 23 crash on Burnt Mountain, near Burrell Place and the Gilmer County line. Robin Stone, a spokeswoman with the Georgia State Patrol, said heavy rain and fog were likely factors in the fatal crash.
