Firefighters from nearly half a dozen departments responded to a fire at a vacant Muskego business on Monday morning.

The fire broke out near Tans Rd & Racine Avenue.

Tess Corners Assistant Fire Chief Mike Wojnowski says the dumpster was directly next to the building, and the roofline of the structure caught fire.

The business is currently vacant, and was going through new ownership.

Wojnowski says that firefighters were able to knock the fire out in about 20 minutes.

He wouldn't say whether they believe the fire was arson or not, but did say the Muskego Police Department is leading the investigation as to how the fire started.
