A fatal accident involving a car and a horse-drawn cart on Green Valley Road in Wayne Township in Knox County on Monday morning is being investigated by the Mount Gilead Post of the Ohio State Highway Patrol (OSHP).

Emma West, 18, of Fredericktown was driving a black 2011 Chevrolet Cruze eastbound on Green Valley Road east of Mile Creek Road at 8:15 a.m. when she struck a horse-drawn cart that also was traveling eastbound. West’s vehicle continued off the right side of the roadway, overturned and struck a tree, the OHSP said.

West was pronounced deceased by medical personnel at the scene.

The horse-drawn cart was occupied by Andy Schwartz, 18, Joel Schwartz, 20, and Amus Schwartz, 21, all of Fredericktown.

Amus Schwartz was transported to Knox Community Hospital with non-life-threatening injuries.

West was wearing a seat belt at the time of the crash. Alcohol and drug abuse are not suspected factors in the crash.
