State troopers are searching for the driver that hit and killed a Duncanville man who was changing his tire on a ramp to the George Bush Turnpike early Monday morning.
The Department of Public Safety said Jason Jones, 26, was struck on a ramp from Belt Line Road to the George Bush Turnpike in Carrollton.
A North Texas Tollway Authority road assistance crew found his body lying next to his Jeep Grand Cherokee at about 3 a.m.
Trooper Lonny Saschel said the cameras on the turnpike are not focused on the ramp Jones was on, making it difficult to make out the license plate of the vehicle that struck him.
"We're in the process of narrowing vehicles down and hope to interview people," Haschel said.
No one witnessed the hit-and-run.
Haschel said Jones pulled over to the safest spot he could.
"He pulled over to right shoulder as close as he could to a concrete barrier -- and just on the other side of the concrete barrier was a 50-foot drop in the water -- so he didn't have much choice. Where he parked was the best that he could," he said.
Haschel said drivers with a flat tire should drive slowly on their rims to get to an exit if needed.
"You can replace rims, not motorists," he said.
Anyone who knows anything about the hit-and-run is asked to call DPS.
The driver who struck Jones could face felony charges for failing to stop and render aid.
