Fire crews from all over the Wyoming Valley were called to Edwardsville to battle a massive blaze at 681 Main Street. Workers at Dancheck’s Extinguisher service smelled smoke and fled. They say they found the building fully engulfed. A mixed martial arts studio is in the front of that structure. Smoke from that Edwardsville fire could be seen for miles. A fire investigator will look for the cause. There were no injuries.
