Donald Donnie Chin, 59, was shot dead in the predawn hours of July 23, 2015, while responding to a dispute in Seattle’s Chinatown-International District. Founder of the International District Emergency Center in 1968, Chin spent decades patrolling the neighborhood, providing first aid and other help when official emergency services were slow to arrive. He was not the intended target, according to the Seattle Police Department, but was struck in crossfire and later died at Harborview Medical Center.

Detectives identified two men who had been in the area and believed to be involved in the violence; one was detained on an unrelated matter, though police did not label either as a suspect at the time. Investigators also examined connections to patrons of nearby hookah lounges and say they have identified the rival groups involved, but a lack of cooperation has prevented charges. Years after the shooting there have been no arrests and the case remains open.

Did anyone in the neighborhood see something that night or know people who were at the hookah lounges before the shooting?
