Three people were shot in Colorado Monday, including a police officer. At first, police said two suspects had been shot, then updated that to say that one of the victims was a bystander who had intervened to stop the shooting, the Colorado Sun reports. The Arvada Police Department released on Friday a timeline of the confusing events. It shows that a man called 911 because he was concerned his brother, Ronald Troyke, was going to “do something crazy.” Officer Gordon Beesley missed Troyke at home, but drove to another call about a suspicious man—who turned out to be Troyke. Before Beesley could even react, Troyke shot and killed him, police say, before returning to his truck for an AR-15. Then, another man shot Troyke and took his AR-15, which he was holding when more officers arrived and shot and killed him.
That man was identified as Johnny Hurley, 40, of Golden, Colorado. Police say Hurley had likely saved lives by stopping Troyke, Colorado Public Radio reports. Police say they found notes in Troyke’s apartment declaring his intent to kill police officers. “Hundreds of you pigs should be killed daily,” one note read. Hurley’s family, in a statement, called his actions “a clear-eyed response to a dire situation,” and said they were looking forward to a thorough investigation. Arvada Police called Hurley’s and Beesley’s deaths equally tragic. Beesley was Arvada Police’s 2014 officer of the year, the New York Times reports. The officer who shot Hurley is on paid administrative leave. (Read more shooting stories.)
