New York State Police, state DEC forest rangers, and more than 300 volunteers are still searching this afternoon for an 18-year-old college student, who’s been missing for nearly three days in the Northern Adirondacks.

Colin Gillis of Tupper Lake was last seen early Sunday along Rt. 3 between Tupper Lake and Piercefield.

Leiutenant Scott Heggelke is with the State Police in Ray Brook. He says police have interviewed more than 100 people, looking for any information that might be useful.

Heggelke says the police remain hopeful, and that teams will continue their search Tuesday until dusk, or until searchers complete the plans rangers laid out this morning—whichever comes first.

Gillis is 6 feet 1 inch tall and weighs 170 pounds. He was last seen wearing a white shirt with black stripes, blue jeans and red sneakers.

If you have any information or think you may have seen Gillis, please call the State Police in Ray Brook at (518) 897-2000.
