Johnson City Police responded to an accident Thursday on East Oakland Avenue near Seventh Day Adventist Church in which a Johnson City man was killed.
According to JCPD Sgt. Jim Tallmadge, William Joey Penix, 58, 1825 W. Lakeview Drive, Apt. D-31, was killed after his vehicle ran off the road.
Tallmadge said the reason for the vehicle leaving the road is still yet to be determined.
"The driver just appears to have lost control of the vehicle. It ran off the road and went up an embankment and overturned at least once and came to rest there against some of the larger trees that were there," he said. "Speed does appear to be ... somewhat of a factor. It's a little early to say if there would be any kind of drugs or alcohol involved."
Tallmadge said police are also looking to see if a medical issue could have played a factor in the wreck.
The investigation is ongoing.
