A Colorado sheriff says police are searching for two people wanted for questioning about Wednesday night's shooting death of a deputy, but says they are not considered suspects.

Adams County Sheriff Michael McIntosh said on Thursday that police believe they have in custody the gunman who shot Deputy Heath Gumm.

McIntosh refused to name the suspect, who was arrested shortly after Wednesday night's shooting in a residential area about 8 miles (13 kilometers) north of downtown Denver. He said releasing the name or photos would compromise officers' investigation.

McIntosh says Gumm and other deputies responded to a call about a disturbance Wednesday. He says the two being sought were involved in that altercation.

Colorado's governor has ordered all flags on state buildings lowered in honor of a sheriff's deputy shot and killed north of Denver.

Gov. John Hickenlooper said Thursday that all flags should remain at half-staff until sunset on the day of Adams County Sheriff's Deputy Heath Gumm's funeral.

The order comes as officers search for two more men wanted in connection with Wednesday night's shooting in a residential area about 8 miles (13 kilometers) north of downtown Denver. Some schools in the area are closed because of the search.

The sheriff's office says Gumm was shot after deputies were called to an "assault in progress" and saw one of the suspects run behind a house. A sheriff's spokeswoman says that suspect pulled a handgun and shot the deputy in the chest before fleeing.

The alleged gunman was found and taken into custody shortly after the shooting.
