Wisconsin ? A helicopter crashed into the roof of a house early Sunday, killing two people in the aircraft, but five people in the house were uninjured, police reported.

The helicopter crashed around 5:30 a.m., about one mile south of the Kenosha Airport, police Sgt. Eric Larsen said.

Fog was reported in the area at the time, but there was no immediate indication if that played a role in the crash. Visibility at 5:30 a.m. was three-quarters of a mile to a mile, National Weather Service meteorologist Chris Franks said.

Federal Aviation Administration spokesman Tony Molinaro said the helicopter was a 2006 Robinson R-44 registered to Midwestern Air Services of Kenosha.
