Taken from the officer's home in southwest Denver were personal belongings and police equipment.
Police are concerned because the suspect or suspects stole several guns, tactical gear such as helmets and vests, and commemorative police department badges.
Police said most of the stolen guns were handguns.
The burglary happened Tuesday afternoon.
Police are concerned not only for the stolen weapons, but also the badges which could allow someone to pose as a police officer.
