Greeley police say officers shot and killed a man who pointed a long gun at one of them.
The shooting happened as they responded to a report of a man outside a home with several guns, including an AR-15 rifle, around 3 a.m. Wednesday.
The Greeley Tribune reported that police said the 911 caller said he was a former member of the military suffering from post-traumatic stress disorder. Soon after that, police say the man talked to a police dispatcher about having a "shoot out".
The man hasn't been identified.
The Weld County District Attorney's office is leading the investigation into the shooting.
