The shootings occurred after deputies responded to a call at about 5:15 a.m. local time to what they thought was a domestic problem at an apartment complex but which turned out to be a disturbance unrelated to any domestic dispute. But some reports suggest that five deputies and two civilians were shot by the suspect, one deputy confirmed deceased.
Authorities in Colorado say five deputies were shot and one has died after a shooting outside Denver.
Two civilian residents of the complex were shot by the gunman and have non-life threatening injuries, Sheriff Tony Spurlock reported at a presser.
A procession for the fallen officer will take place from Littleton Hospital. "Please avoid this area".
