On a summer's night, gunfire rang out after a teen party in Lower Price Hill. There, on the ground, witnesses found the body of a 14-year-old boy, Cameron Franklin.  Despite the many calls to 911 and witnesses nearby, no one has been charged with the murder. In this episode, Detectives Horn and Kelley walk us through the evidence and explain how the gun used to kill Cameron was used in at least three more shootings.
