On the evening of July 26, 2012, 16-year-old Kiera D. Tanter was among a group of friends gathered in Gravois Park at Miami and Louisiana Avenues in St. Louis when multiple gunshots rang out around 9:15 PM. An unknown person or persons opened fire, wounding five people. Kiera and her friend Ronisha Jackson were critically injured, transported to a local hospital, and pronounced dead from their gunshot wounds.

The shootings remain unsolved. No arrests have been announced in connection with the murders of Kiera Tanter and Ronisha Jackson, and investigators have appealed to the public for information. St. Louis Regional CrimeStoppers has offered a reward for tips that lead to an arrest.

If anyone knew Kiera or was at Gravois Park that night, does any detail from that evening stand out that could help investigators?
