John J. Myles, 45, was killed in Chicago on April 29, 2014. His death was one of many gun-related homicides that year as the city struggled with persistent violence, especially on the South and West Sides.

The case is presented against a broader backdrop of 2014’s high homicide rate and the systemic problems cited as contributing factors: economic instability, gang-related activity, and limited violence-prevention resources in the hardest-hit neighborhoods. Myles’s homicide is recorded in the Chicago Police Department’s crime tallies for that year.

Anyone who knew John Myles, witnessed the incident, or has information that could help investigators is asked to come forward.
