MARION COUNTY –A 54-year-old Central City man was killed Saturday afternoon in a one-vehicle crash on Green Street Road.

According to Marion County Coroner Troy Cannon, John W. Oettle was traveling westbound on Green Street Road approximately 100 yards east of Brick Hill Road just east of Central City.
