Investigators believe someone may have broken in and lit a fire inside St. Charles Parish School early Thursday morning. Spokane Fire crews said there was a possible explosion reported inside the school around 1:40 a.m. and flames could be seen throughout the roof. Spokane Police later said the incident was “not accidental.” A priest was inside the building, but police were able to get him out uninjured before fire crews arrived. When firefighters did a sweep of the building, they did not find anyone inside. The investigation is ongoing and at last check, arson investigators were on scene.
