On the evening of April 23, 2016, Derrick Wren, 42, was shot outside a bar at 57th Street and Troost Avenue in Kansas City, Missouri. Just before 8 p.m. an argument outside the bar turned violent; surveillance footage captured a physical fight involving Wren and two other men, and during the altercation one man fired multiple shots. Wren was taken to a nearby hospital but died of his injuries, recorded as Kansas City’s 28th homicide that year.

Investigators recovered nine shell casings and personal items at the scene, including a pair of broken eyeglasses. Those items and the surveillance video were central to identifying a suspect; witnesses later picked out a man they said was the shooter. Court documents note the identified suspect had a black eye and mentioned having recently bought new eyeglasses.

If anyone was near 57th and Troost that night or has information about the fight or the people involved, please share what was seen or heard.
