Samuel Walker Jr., known as Lil’ Sam, was 13 when he was shot and killed on July 25, 2014, on Chicago’s West Side in the East Garfield Park neighborhood. The same shooting wounded six other people during a summer already marked by violence in the city. Samuel is remembered by his community as a cheerful, caring boy who always made people laugh. Authorities linked the attack to gang activity, and in October 2014 three men were charged in connection with the incident. Samuel’s death deeply affected his family and friends and underscores the toll of gun violence in Chicago’s neighborhoods.

If anyone knew Samuel, saw activity in East Garfield Park that day, or has information relevant to the case, please share what you know.
