An autopsy shows that eight-year-old Camille Thibeault died from asphyxiation.

The girl's body was found face-down in the snow near her home in Saint-Felix-d'Otis in the Saguenay region of central Quebec.

Her family was puzzled by how the girl could have died while simply playing in the snow.

The coroner says the girl probably fell down, was knocked unconscious and died from asphyxiation.
