A 78-year-old man died in a Sunday morning house fire in the southeastern community of Saint-Louis-de-Kent.

RCMP say police and fire crews were called to a small trailer around 9 a.m. on Sunday.

The trailer was on fire when crews arrived and firefighters discovered a 78-year-old man collapsed behind the front door.

He was unresponsive when he was pulled from the burning trailer.

Police say it appears he died from smoke inhalation.

The man lived alone and no one else was in the building.

His name has not been released.

The Office of the Fire Marshal is investigating, but it's not considered suspicious.
