Tyler J. Smith, 14, was airlifted to the Georgia Regents Medical Center, where he was pronounced dead at 12:16 p.m., according to Columbia County Coroner Vernon Collins.
Kenneth Gill, 58, of North Augusta, was charged with first-degree vehicular homicide.
Tyler and his 6-year-old brother, Jonathan, were hit by Gill’s east-bound Dodge pickup just after 11 a.m. The boys were on the shoulder of the 4500 block of Hardy McManus Road.
Columbia County sheriff’s Capt. Sharif Chochol said it appeared Tyler was sitting on a go-kart and his brother was standing nearby when the truck veered onto the shoulder and plowed into the go-kart before coming to a rest at the base of a steep embankment across from Woodruff Way.
Columbia County sheriff’s Capt. Steve Morris said Gill was distracted when he went off the road.
Scott Stephens said he and his wife arrived on the scene just after the accident occurred. He said Tyler’s mother waved him down, so he pulled over.
Stephens said when he got to the truck he saw Tyler was pinned beneath one of the truck’s rear wheels. He said several people quickly came to the boy’s aid.
“We just jumped in and pulled the truck off of him and started CPR,” Stephens said.
Chochol said he wasn’t sure how badly Tyler’s brother was injured, although he said it did not appear to be serious.
“We think the truck just scraped him; we’re not sure,” he said.
He said the crash is under investigation.
Collins said an autopsy will be performed on Tyler at the Georgia Bureau of Investigation Crime Lab in Atlanta.
