The Mt. Morris City Police Department said an investigation found nothing suspicious or criminal about the explosion around 11:15 p.m. on April 15. The explosion leveled a building that once house Old Time Billiards and Lucille Allen Ladies Apparel.

No injuries were reported. Investigators from various agencies, including Consumers Energy, concluded a contractor improperly installed the furnace and natural gas leaked indoors. The buildup of gas exploded when it ignited.

The remainder of the building will be razed soon. Parts of the intersection of Saginaw Street and Mt. Morris Road remain closed due to debris from the building falling onto the streets.
