FAIRBANKS -- A search has been called off for a Delta Junction man missing for four days.

The Fairbanks Daily News-Miner reported that Alaska State Troopers ended the search Thursday for 20-year-old Emmanuel "Martin" Hosier.

Trooper Steve Lantz said it's likely Hosier fell into the Tanana River. Hosier has been known to climb both the bluff and the bridge on the river.

His vehicle was found Monday at a pullout near the river north of Delta Junction. He was last seen on Sunday.
