BOISE, Idaho -

 A search in the central Idaho backcountry for five people in a small plane that disappeared Sunday has been complicated by heavy snow and low visibility.
    
The Idaho Statesman says the state Transportation Department reports that the search was halted Monday evening but was to resume at daybreak Tuesday.
    
Valley County sheriff's Lt. Dan Smith said earlier that about two dozen search and rescue personnel were combing a mountain ridge near the tiny town of Yellow Pine for a single-engine Beech Bonanza.
    
The plane carrying five family members was flying from Baker City, Ore., to Butte, Mont. The pilot had reported engine troubles.
    
Authorities have not identified the occupants.
    
Federal Aviation Administration records show the plane's registered owner is Dale Smith, of San Jose, Calif.
