Police said that Robert Lee Pinkins had last been seen leaving his home to go to the Walmart store in Raeford Road. A Silver Alert was issued for him around 3 a.m.
Later Sunday morning, a state trooper found Pinkins along Interstate 95, police said. His truck had run out of gas, but Pinkins was OK.
Developed in 2007, Silver Alert is a system to quickly notify the public about missing endangered adults who suffer from dementia or other cognitive impairments, such as Alzheimer's disease.
It also allows caregivers and nursing homes to report a person missing. In the past, only a family member could report an adult missing.
