On the afternoon of August 2, 2011, 27-year-old Rapid City Police Department officer Nicholas Keegan Armstrong was shot during a routine contact at East Anamosa and Greenbriar Streets in Rapid City, South Dakota. Officers Armstrong, J. Ryan McCandless, and Tim Doyle had stopped to question a group of four people who appeared intoxicated when one of them, Daniel Tiger, produced a concealed .357 caliber revolver and opened fire. The first shot struck Armstrong in the chest, passing just left of his protective vest and incapacitating him.

Tiger also shot Officer Doyle in the face; McCandless, though critically wounded, returned fire. All three officers were taken to a local hospital. McCandless died shortly after arrival; Armstrong survived for five days but died on August 6, 2011, from the single gunshot wound. Tiger was fatally wounded in the exchange. Investigators reported Tiger had a lengthy criminal history and had told a witness he wanted to die, discussing the idea of suicide by cop; the investigation found the officers’ use of lethal force justified.

If anyone knew Armstrong, the other officers, or the people involved at that intersection, please share what you remember.
