Ten people were inside the two-unit house at the time the fire broke out, sometime between midnight and 1 a.m. Saturday. All but one — a man in this forties — managed to escape.

Today, the small community about 80 kilometres northwest of Montreal was reeling from the devastation. 

Neighbours reported hearing an explosion around 1 a.m. Saturday.

"My wife woke me up to tell me the house at the top of the street was on fire," said Jacques Lussier.

A woman was heard screaming at her husband to not go back inside the house, neighbours said.

The search for the man's body ended successfully around 3 p.m., but the reason why he went back inside is still unknown. Some neighbours suggested he was looking for his dog.
