COLORADO — (Scroll down for video) — On December 31, 2017, a shooting occurred in Highlands Ranch, Colorado, where five deputy sheriffs were shot. One deputy was shot dead, and four others were injured. Two civilians were also shot by the suspect, who was later killed in a firefight with police. The suspect reportedly used a rifle and a shotgun. Law enforcement had responded first to a noise complaint to the apartment, then to a domestic-disturbance call to the apartment.
The suspect reportedly barricaded himself in his bedroom and shot the deputies in an “ambush” style when they entered. The suspect was later shot dead by a police tactical team that subsequently re-entered the apartment.
