Nicholas Ellingson was involved in a tragic incident on December 17, 2020, in Auburn, WA, when police responded to a call about a disabled vehicle obstructing the roadway. Upon arrival, officers identified Ellingson, who had two outstanding warrants, and attempted to detain him. In a bid to escape, Ellingson fled on foot, during which he displayed what officers perceived to be a firearm. This led to an officer firing his weapon, resulting in Ellingson's death at the scene despite immediate medical assistance. The Auburn Police Department released an initial press statement with limited details shortly after the incident, stirring community concern.
