Hendricks County Sheriff's Cpt. Brett Clark told the BannerGraphic that 71-year-old Glenn E. Cobb, Heritage Lake, died when his 1993 Cutlass Cierra veered off the roadway, rolling over and then striking a power pole.
The accident occurred at around 12:15 p.m. in the 800 block of Ind. 75 South, according to a sheriff's department report.
Cobb's wife, 72-year-old Mary Ann Cobb, who was a passenger in the car, was taken to Hendricks Regional Health in Danville and was treated for lacerations on her face and head. Her condition was not known as of Tuesday morning.
Clark said the officer who investigated the scene said it appeared Cobb suffered some type of medical condition which caused him to lose control of his car and drive off the road. There were no other cars involved in the accident.
Officers ruled out weather or alcohol as causes, Clark said.
Hendricks County Coroner Jason Matthews told the BannerGraphic he would perform an autopsy on Cobb this afternoon to determine if he died as a result of the accident or because of his ongoing medical condition.
Matthews said Cobb had a pre-existing heart condition and that "there is some indication" that it caused the accident.
