According to a KSP news release, CVE Officer Derek Cundiff responded to a collision at 9:10 a.m. Friday, 10 miles south of Campbellsville on KY 55.
Donnell York, 83, of Columbia, was driving a 2008 Chevy Impala north. A witness to the crash told KSP troopers that York pulled off the shoulder of the roadway, slumped over the steering wheel, briefly stopped before taking off again, crossed the center line and struck a guardrail before coming to a final rest in the ditch line.
York was transported to Taylor Regional Hospital. Taylor County Coroner Terry Dabney pronounced him dead of natural causes.
The report states that Dabney believes York likely died from natural causes, but can't confirm that cause of death without toxicology results, which are pending.
The case remains under investigation.
