CHICAGO (MCT) — As Chicago struggles with its highest murder rate in years, the role of a single street gang stands out: more than a quarter of the city’s nearly 400 homicide victims through Sept. 25 were affiliated with the Gangster Disciples, according to police statistics obtained by the Chicago Tribune.

Long the city’s largest gang, the Gangster Disciples have dominated significant swaths of the South Side for decades. But now authorities say the gang is eating itself up from within, riven by feuding factions with names like the “Killa Ward” and “The Hit Squad” that engage in bloody conflicts over turf they once shared.
