The Utah Highway Patrol says it appears a 49-year-old man suffered a medical event, possibly a heart attack, and died while trying to drive himself to a Cedar City hospital.
UHP Sgt. Todd Royce said the man was found dead in his car Monday. His Ford F-150 pickup truck had drifted off the eastbound lane of Highway 56 near mile marker 33, just west of Cedar City.
"What we are looking at is that this was a medical issue. There was no evidence of any braking prior to the truck leaving the road," Royce said on Tuesday.
