The roadside is littered with glass, wiring, mirrors and door handles that snapped off the 2007 Kia Scottie Privette and his wife, Jeanette, were traveling in Thursday night.
Troopers said the 41-year-old man was killed when he lost control of his car in a curve not far from the Chesterfield County line.
The car swerved off the road, overcorrected, then rolled several times.
Privette was not wearing a seat belt, and was thrown out onto the rural highway. Moments later, troopers said a man driving by didn't see him in the darkness and struck his body. Lancaster County Coroner Mike Morris told Eyewitness News that an autopsy Saturday could help determine if Privette died when he was ejected from his car, or after he was struck.
Privette's wife Jeanette was wearing a seat belt, and was airlifted to Palmetto Richland Hospital in Columbia. Her condition was not available late Friday.
"I'm gonna miss him. He was the only family I got left," said Privette's younger brother Frankie Bowers.
Bowers told Eyewitness News that the family lives in Jefferson, South Carolina in Chesterfield County. He had last seen his brother a few days after Christmas.
"We were always close," he said. "Now it's just me in our family"
Lori Torres grew up with the couple, and can't understand what happened.
"He was a really good driver," Torres said. "I don't really know what happened. I'm just confused about all this right now."
Bowers said he didn't know where his brother and sister in law were going so late last night, but suspects they were just making a quick run to a convenience store.
Troopers don't yet know why Privette lost control of his car, or how fast he was going. They did reconstruct the crash to try to find those answers.
The area is about 15 miles east of Lancaster. It's very rural, with no houses, street lights or businesses.
Morris told Eyewitness News it was very cold, windy, and there was a heavy mist that might have made the roads slick. Road conditions have not been ruled out as a possible cause of the crash.
Torres just worries about her long-time friends, and their pain.
"They'll be alright. It's just gonna be really hard for the next few days," she said.
Troopers did not charge the 77-year-old Lancaster man who struck Privette as he was lying in the road. He and his passengers were not hurt.
