Samuel Powers, 73, was last seen in Levittown, New York, on June 22, 2015. At the time he disappeared he was wearing a white short-sleeve shirt, gray dress pants, brown work boots and his glasses. Family and authorities were concerned because Samuel was believed to be experiencing the possible onset of dementia, making him a vulnerable adult who might be disoriented or unable to seek help.

The Nassau County Police Department investigated the disappearance. A troubling lead indicated Samuel might be in Miami, Florida, a development that expanded the search area by more than a thousand miles and added a difficult geographic dimension to efforts to locate him. Weeks became months and then years without resolution, leaving his family without answers.

If anyone has information about Samuel’s whereabouts or recalls seeing a man matching his description in June 2015, please come forward.
