On October 10, 2020, in downtown Denver near the Denver Art Museum, 49-year-old Lee Keltner was involved in a confrontation during opposing political demonstrations. Keltner, a custom hat maker, U.S. Navy veteran, husband, father and grandfather, had been attending a Patriot Rally. A verbal dispute escalated into a physical altercation in which Keltner was seen holding a can of pepper spray and struck 30-year-old private security guard Matthew Dolloff on the side of the head with an open hand.

Almost immediately after that blow, Keltner discharged pepper spray as Dolloff drew a handgun and fired a single shot. Keltner collapsed, was taken to a nearby hospital and died later that afternoon; the Denver Medical Examiner ruled the death a homicide. Police took Dolloff into custody at the scene and recovered a semi-automatic handgun.

If anyone witnessed the events near the museum or has additional information about the confrontation, please share what was seen or heard.
