TAFT, Okla. (AP) — Authorities say one person was killed and seven were injured in a shooting early Sunday at an outdoor festival in eastern Oklahoma. The Oklahoma State Bureau of Investigation said in a statement that two juveniles were among those shot at the Memorial Day event near Taft, about 10 miles southeast of Tulsa. The agency reports that witnesses said an argument preceded the gunfire just after midnight. No one has been arrested. OSBI says about 1,500 people attended the event and that members of the Muskogee County Sheriff’s Office who were also in attendance immediately rendered aid to those who were shot. The agency provided no other details including the conditions of the injured.
