WHEAT RIDGE - Investigators have now completed an inventory of the guns stolen from A Wheat Ridge gun shop featured on Discovery Channel's "American Guns."

Wheat Ridge police say 12 handguns and three rifles were taken from the Gunsmoke Gun Shop at 9690 West 44th Avenue. No weapon that could be classified as an assault weapon was stolen.

Wheat Ridge police were notified of a silent alarm at the shop just before 4:15 a.m. Wednesday. When they arrived, they found that the shop had been entered through a hole in the roof.

Police say a witness across the street reported seeing a silver two-door car leaving the gun shop's parking lot, shortly after the silent alarm was received.

Police say it appears more than one person may have been involved in the burglary. Investigators had no suspect descriptions.

The Bureau of Alcohol, Tobacco and Firearms and Explosives is assisting local investigators.

Anyone having information that may be connected to this case is asked to call the Wheat Ridge Police Department Tip Line at 303-235-2947.
