A 15-year-old was arrested Sunday night after the shooting near Florida A&M University's Bragg Memorial Stadium and was charged with 11 counts of attempted second-degree murder plus firearm possession by a delinquent.
Tallahassee police said 12 people were injured in Saturday's gunfire, including six juveniles; the youngest victim was 11 years old.
An altercation preceded the shooting, and investigators are still working to determine what led to the violence and whether others were involved.
Police Chief Lawrence Revell called the arrest a significant step but said the investigation remains active as authorities seek answers for the victims' families.
