Crews in western Newfoundland say their search for an American hunter whose truck was found grounded in a deeply wooded area is now a recovery mission.

William Oberkiser, 65, of Indiana was reported missing last week.  His truck was found stuck on a tree stump on an unpaved path about 15 kilometres from the Trans-Canada Highway.

 Searchers have to date been unable to find any sign of Oberkiser, whose locked truck was found untouched, and still included his personal papers, hearing aids and guns.

Family said he had been heading for a hunting trip in the Buchans area.

Police met with ground search and rescue teams from Stephenville and Barachois Brook on Monday morning, before a sweep of the area began. Dog units from the Royal Newfoundland Constabulary are also working on the search.

Barachois search and rescue co-ordinator Barry Nash said the search is scaled down from the effort last week.

"Today, they will probably work till dark and then it will be reassessed as it is every day, on a day-to-day basis in conjunction with the RCMP," he said.

The search has involved more than 20 people, a helicopter crew and an amphibious all-terrain vehicle supplied by the Department of Fisheries and Oceans.
