POTSDAM -- An overnight search involving approximately 225 volunteers and law enforcement officers led to the discovery of an 81-year-old man who went missing Monday afternoon.

"We are very fortunate," said Potsdam Volunteer Fire Department Assistant Chief Justin Perry.

Perry said the search lasted approximately 15 hours, with rescuers scanning wooded areas along the South Canton Road throughout the night, before the man was discovered at a residence.

Perry said the man believed to have spent the night outside.

He was located early Tuesday morning and was transported to Canton-Potsdam Hospital for evaluation.

Perry said he was uncertain of the man's medical history or current condition, but said he was conscious when he was found.

Perry said volunteer firefighters from Canton, West Potsdam, West Stockholm, Hannawa Falls, Brasher, Parishville, Norwood and Norfolk participated in the search.

New York State Police, United States Border Patrol officers, New York State Department of Environmental Conservation officers, St. Lawrence County sheriff's deputies and St. Lawrence County Emergency Services workers aided in the search.

"We had a lot of help," said Perry. "It ended very well."
