Nicholas Simmons disappeared from his parents' house in a small upstate New York town on New Year's Day, leaving behind his wallet, cellphone and everything else.
Four days later, an Associated Press photographer, looking for a way to illustrate unusually cold weather, snapped his picture as he warmed himself on a steam grate a few blocks from the U.S. Capitol.
Paul and Michelle Simmons saw the AP photograph in USA Today Sunday morning after it was brought to their attention through a Facebook page set up to help find their 20-year-old son, according to police and family friends. (AP)
