Unalaska, AK – The State Fire Marshal has determined the cause of the fire at Peking Restaurant to be unattended cooking. Something was unintentionally left cooking on the stove, it caught on fire, and the fire spread from there. The building will need substantial repairs, such as fixing the holes cut in the roof and ceilings by fire fighters who were trying to extinguish the burning structural beams. It now also needs to be brought up to current fire code standards. The building was originally built during World War II. It's unclear when businesses will be able to resume operations in the building.
