Great Bend, ND – A malfunctioning propane heater in a garage is the suspected cause of an explosion and fire at a residence in Great Bend.

The only occupant of the house, 76-year-old Don Leinen Sr., was unharmed. He was rescued by his son, who is a volunteer firefighter.

Fire chief Pat Porter says flames were 40 to 50 feet in the air when fire units arrived around 3 o’clock Monday morning.

The house is considered a total loss.
