MOSCOW, Idaho--Fire investigators say an undetected fire in the attic of a Moscow apartment complex caused an explosion late last week.
The explosion on January 19th tore large holes through the Elysian apartment complex.
Investigators say the fire has burned for an unknown amount of time and wasn’t detected by the building’s residents before the explosion. They say the explosion was caused by a combination of heat, smoke and carbon monoxide gas in the attic and its blown-in attic insulation. Investigators say those factors combined caused a smoke explosion in the building.
Officials say the utility chase and furnace were the point of origin for that fire in the attic.
No one was seriously hurt but 8 people lost their homes.
The explosion damaged the roof structure, inside walls and ceilings on both floors.
Officials say the investigation is ongoing.
