Cecil Olive was found on New Hill Olive Chapel Road just after 2:30 p.m.
Olive's family said they spent a few hours searching for him Thursday before calling 911 at 10:30 p.m.
Olive is believed to have dementia or Alzehimer's disease.
"The more time that passes by, the more distance that could be occurring. And we don't have any idea at this point if he got in a car with someone, if he's still on foot, if he's laid down somewhere because he's tired. That'd be perfectly understandable, so we just don't know ," Tony Godwin said.
