Martell L. Robinson, 20, was fatally shot on September 8, 2014, in an alley in the Roseland neighborhood of Chicago. His killing occurred during a particularly violent year for the city, when hundreds of homicides were recorded and many neighborhoods struggled with recurring gun violence.

His death is presented as part of a larger pattern that prompted heightened attention from law enforcement and local authorities but also underscored persistent structural problems.

If anyone knew Martell, witnessed the shooting, or has information that could help shed light on what happened in that Roseland alley, please come forward.
