GRAND FALLS, New Brunswick -- The search for a man who jumped into the Grand Falls gorge in New Brunswick near the Maine border has been suspended indefinitely.

Grand Falls Police Chief Jean Real Michaud says the St. John River is too murky to conduct an effective search.

Divers were brought in Wednesday along with dozens of firefighters and volunteers to search the area near a tourist center. That's where witnesses saw a young man dressed in a black shirt and black pants climb a fence, walk out onto the rocks and leap into the deep gorge Tuesday night.

Michaud says there have been no reports of a missing person and the man's identity remains a mystery.
