CHERAW — Police are awaiting an autopsy to determine what caused a man to cross three lanes of traffic crashing into a doctor’s office sign.

Reggie L. Melton, 47, was pronounced dead at the scene April 7 when a Henley Construction work truck he drove collided with a Cheraw Family Medicine sign during afternoon traffic.

Without autopsy results in hand, police are speculating the cause of the wreck may have been medical related.

“There is no indication of any other reason why one would veer three lanes of traffic, jump a curb and never touch the brakes,” said Cheraw Police Cpt. Keith Thomas.

However, autopsy results are pending before police make an official conclusion.

State troopers investigating the wreck are pulling information from the truck’s computer system to determine when and if the truck accelerated or braked leading to the crash.

Melton was behind the wheel of a Chevrolet 2500 HD heading into Cheraw on S.C. Highway 9.

Witnesses reported seeing the Henley Construction truck veer onto the median entering oncoming lanes of traffic.

“One of the closest witnesses slammed on the brakes as he jumped the curb,” Thomas said.

The motorist, who was nurse, was the first at the scene.

A First Health EMS crew leaving Chesterfield General Hospital immediately saw the wreck scene; workers were unable to remove Melton from the truck, calling for Cheraw fire and rescue.

Melton was deceased by the time rescue workers were able to remove him from the truck, Thomas said.

Funeral services were held April 10 at Cedar Creek Baptist.

Melton was survived by a wife and two daughters.
