The Michigan State Police Bomb Squad has been called in to clear a home on Louise in Highland Park.
Sources tell Local 4 that it all started with a warming fire that a squatter had started.
Once the fire was extinguished, firefighters found a cache of guns.
According neighbors, the homeowner passed away a couple months ago and the house had been boarded up to prevent trespassers.
A Local 4 photographer on the scene has counted at least 20 guns that have been removed from the house.
