SIREN, Wis. (AP) -- Residents in Minnesota and Wisconsin are cleaning up from a fierce storm whose heavy winds toppled trees that killed an 11-year-old girl and injured more than three dozen people.

The Friday storm tore roofs off buildings, blew in garages and left thousands without power.

Wisconsin authorities say three of the 39 injuries were critical. Emergency officials originally attributed two deaths to the storm but later said one death was an apparent heart attack that might be indirectly storm-related.

Injuries were also reported in Minnesota's Douglas and Meeker counties.

A search continued Saturday for missing canoeists along the St. Croix River.

Wisconsin authorities say the wall of an airport hangar collapsed in Douglas County, causing the building to collapse on a single-engine plane.
