Police radio transmissions indicated the suspect, Felix Trujillo, donned a sheriff's deputy uniform and walked out of the jail about 7 p.m. A department release on the incident said the suspect "may be armed and should be considered extremely dangerous."
The Denver Post said Trujillo has an extensive arrest record.
KCNC-TV said Deputy Matthew Andrews is suspected of aiding Trujillo in his escape. Andrews allegedly provided a department coat, gun belt, pants and hat to Trujillo to help him escape, sources told the CBS affiliate.
