Mason Mitchell, a 25-year-old White man, was shot during a confrontation at El Dorado Park in Scottsdale on January 4, 2017, and later died of his wounds. The incident is described as an altercation that escalated to deadly violence and prompted local news coverage.

A 58-year-old man named Gary Rinsem was arrested in connection with the shooting. Rinsem maintained that he fired because he believed it was the only option available during the dispute, a claim that has contributed to debate over the use of force in the case.
