A US law enforcement officer was killed and seven other people, including five officers, have been wounded before police killed the gunman in a residential suburb near Denver, Colorado.
The gunman opened fire on sheriff’s deputies who were responding to an emergency call on Sunday in Highlands Ranch, 12 miles (20 kilometers) south of Denver, the Douglas County sheriff’s office said in a statement.
The suspect was shot and believed to be dead after the standoff. Police from five jurisdictions, including Colorado state police, were placed on alert.
Residents in the vicinity were advised to stay inside and avoid exterior walls and windows.
The wounded were taken to two area hospitals, at least three of them with noncritical injuries, the Denver Post reported.
