Robert Wayne Powell-Moore III was 18 when he was shot and killed in Dubuque, Iowa, on the afternoon of Saturday, July 17, 2021. Police found him with a gunshot wound to the chest near 14th Street and Central Avenue; he was taken to UnityPoint Health-Finley Hospital and pronounced dead.

Investigators say Powell-Moore had been involved in an altercation with two other teenagers in an alley behind 1401 Central Avenue. City traffic cameras reportedly recorded the incident and helped law enforcement locate suspects at a Jackson Street residence. A 15-year-old male and a 14-year-old female were taken into custody and charged with voluntary manslaughter and carrying weapons; their names have not been released because they are juveniles.

Powell-Moore had just graduated from Dubuque Senior High School in 2021 and planned to play basketball at the University of Dubuque. Does anyone have information about the alley behind 1401 Central Avenue or saw activity near 14th and Central on July 17, 2021?
