Johnson was killed when police said there were several fights between teens on Glenwood Avenue. 

"No one expects a 15-year-old to be gunned down in the city of Atlanta. We take this seriously, as Chief [Rodney] Bryant said earlier. I think we have the best homicide unit," said Deputy Chief Hampton.

Police responded to the incident shortly before 10 p.m. The Waffle House window was shattered by gunfire.

Johnson's death was one incident in a string of violent crimes from the weekend

Atlanta Police Department Chief Rodney Bryant called Johnson's murder "significantly traumatic" and says the city will work "diligently to bring closure to this case."
