On May 3, 2020, Austin AJ Nielsen, a 22-year-old White male from Greeley, Colorado, was shot and later died at a hospital after an exchange of gunfire on the 1200 block of 18th Street, near the University of Northern Colorado campus. Nielsen was in the driver’s seat when he was shot in the head; his vehicle then accelerated, struck two other vehicles at 11th Avenue, and he was taken to a local hospital where he died shortly afterward.

The Greeley Police Department’s investigation found Nielsen had arranged to meet a 17-year-old male to sell marijuana. An argument over price escalated, and both drew handguns and shot each other. The juvenile was hit in the chest, stumbled down the street, collapsed, and was pronounced dead at the scene. Investigators recovered both handguns and spent shell casings. The department concluded the two had fatally shot one another, and no arrests were made.

Did anyone in Greeley know either man or have information about the meeting that led to this confrontation?
