NASHVILLE, Tenn. (WKRN) – The cyclist who was injured when he was hit by a car while on Natchez Trace Sunday has died from his injuries.

Vanderbilt University Medical Center spokesperson confirmed to News 2 Randall Singleton passed away Wednesday night.

According to investigators with the National Park service, a driver in a 1965 Ford Falcon ran into the 58-year-old man. He suffered significant head and leg injuries.

The victim’s son, Randall Singleton II told News 2 he knows the area of the trace where his dad was hit and he went back to investigate. He said he didn’t find much after investigators picked up the scene.

“He was hit – not just clipped. He was hit really hard,” he said.

The driver stopped, and according to rangers, has been cooperating with investigators.

According to a report obtained by News 2, the lifelong mechanic and father suffered a serious head injury. He was airlifted to Vanderbilt University Medical Center in Nashville where he died.

Rangers said the cyclist had a recording device on his bike at the time, but investigators said there was not any video showing the crash.

“[I] can’t be completely angry at this person because I don’t know the situation,” his son said.

Investigators said there are no witnesses other than the people in the Ford Falcon.

Investigators told News 2 the investigation could be lengthy since park police are doing their own reconstruction of the accident.

Anyone with information is urged to call investigators at the U.S. National Park Service at 662-680-4014.
