More ground searchers will be deployed Wednesday as authorities in Wyoming look for a small plane that dropped off radar.
Officials have been unable to locate the plane, with four people on board, since it took off from Jackson Hole Airport Monday afternoon.
Det. Sgt. Ryan Lee of the Fremont County Sheriff's Office said Tuesday searchers were working in a very remote area of the county with elevations around 13,000 feet.
Snow storms, high winds and low visibility have hampered the search, Lee said. He said authorities would not release the identities of those on board pending notification of family members and also would not say whether there were children aboard.
The Minneapolis Star Tribune had reported that the plane carried the president of a Twin Cities web development company and three children.
