Sean A Avery, 22, was shot and killed on July 24, 2011, in the Avalon Park neighborhood on Chicago’s South Side. He was found with a gunshot wound to the abdomen in the 8200 block of South East End Avenue and died shortly after being transported to a local hospital.

Avery’s death occurred during a particularly violent summer in Chicago, when multiple shootings and other victims of gun violence were reported across the city. The 2011 Chicago Murder Report attributed much of that year’s homicide total to interpersonal disputes, gang-related violence, and systemic factors such as poverty and the accessibility of firearms.

If anyone knew Sean Avery or has information about the shooting in Avalon Park on July 24, 2011, please share what you know with investigators.
