DEFIANCE, Oh. (WOWO):  The Defiance Patrol Post is investigating an early morning crash that has left one man seriously injured.

James A. Wolfrum, 28 of Ney, Ohio was driving his Ford Explorer eastbound on County Road 424 in Delaware Township.  At around 3:30 a.m. Saturday morning he approached Limbaugh Road and drove off the north side of the road, striking a guardrail.  His vehicle slid on top of the rial, eventually flipping several times. 

Wolfrum was traveling alone and not wearing a seat belt, and alcohol is suspected to be a factor in the crash.  He was taken to the Defiance Regional Hospital where his condition has not yet been released.
