As Thaw From Buffalo's Deadly Blizzard Begins, Troops Check For More Victims

National Guard troops trudged door-to-door on Wednesday looking for winter storm victims who may be unaccounted for in parts of Buffalo hit by prolonged power outages, after a deadly Christmas blizzard that buried New York's second-largest city in blinding snow.

The fiercest blizzard to strike western New York in 45 years was part of a wider winter storm front and arctic blast that drove freezing temperatures as far south as the Mexican border for days, leaving scores dead nationwide, including at least 38 in the Buffalo area.
