Wheat Ridge police were notified of a silent alarm at the Gunsmoke Gun 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 Wednesday afternoon, and an inventory of stolen property was not yet complete.
The Bureau of Alcohol, Tobacco and Firearms and Explosives is assisting local investigators.
