Tommie Gene Burke, 77, was taken to a local hospital as a precaution, Emerald Isle police said.
Burke had last been seen at the Carteret County Solid Waste and Recycling Station, and authorities issued a Silver Alert from him Saturday afternoon.
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.
