Fifteen-year-old Alejandro Valdez was shot and killed on August 21, 2012, in Chicago’s Lawn neighborhood. While walking on South Talman Avenue he was struck by a bullet in the back and was taken to Mount Sinai Hospital, where he later died.

His death was one of many that year tied to rising gun violence in the city, leaving family and the community mourning a young life lost to senseless violence.
