The bodies of a Canadian couple and their two daughters were found late Tuesday in the basement of their house that plunged into a massive sinkhole, CNN affiliates reported.
"They were found very close to one another, some of them lying on the couch in the family room in the basement, where we were told that they'd be," said Michel C. DorĂ©, Quebec's associate deputy public security minister, who was on the scene, told CNN affiliate CBC.
Yvon Desrochers, uncle of homeowner Richard PrĂ©fontaine, told the CBC on Tuesday feared his nephew and his family were in the basement watching the Montreal Canadiens-Pittsburgh Penguins hockey playoff game Monday night when the ground gave way beneath the home, about 40 miles northeast of Montreal.
Besides PrĂ©fontaine, those in the home were his wife, Lyne Charbonneau, and their two daughters, AmĂ©lie, 12, and AnaĂŻs, 9.
The familyâ€™s dog was found alive â€“ caked in mud â€“ in the sinkhole earlier Tuesday.
The hole was about 500 yards long and forced the evacuation of five other homes in the town of Saint-Jude, in a rural area near the Yamaska River.
While there was no official word on the cause of the sinkhole, geologist Judith Patterson told CNN affiliate CTV that the sinkhole looked like a kind of landslide known as a â€ślateral spread.â€ť
The region has soils known as â€śquick clayâ€ť that can liquefy, leading to a landslide or sinkhole, she told CTV.
"These clays, they're stable when they're undisturbed. But once they're disturbed, then they become very hazardous," she told CTV.
