Ronnie Montgomery, 24, was fatally shot in Chicago’s University Village neighborhood just after midnight on May 16, 2015. He was found with multiple gunshot wounds and was pronounced dead at the scene.

His death occurred during a particularly violent weekend in the city that included another fatality and at least 40 people injured in a series of shootings, a spike that underscored ongoing problems with gun violence and the difficulties law enforcement and the community face in addressing it.

Anyone who was in or around University Village that night or who has information about Montgomery’s shooting is asked to come forward.
