Investigators in Tomah are probing an explosion associated with a fire that engulfed downtown premises last Friday.
Fire Chief Tim Adler has enlisted external expertise to examine the blast preceding the inferno that razed the Sassy Girl Aroma shop.
Although no casualties were reported in either the explosion or the subsequent fire, two firefighters sustained minor injuries during suppression efforts.
While ruling out a natural gas leak, Chief Adler refrains from disclosing other potential causes pending the investigation.
This incident follows closely on the heels of another downtown fire that gutted a Chinese restaurant a few months prior.
