TAFT, Okla. (KFOR) – One person was killed and seven others were sent to a hospital after a shooting at a Memorial Day festival in Taft, Oklahoma Sunday morning.

According to the Oklahoma State Bureau of Investigation, at least 1,500 people were in attendance at the annual outdoor festival in Taft’s Old City Square. Witnesses told police that an argument started just after midnight and shots were fired.

“It was traumatizing, a lot of people here are traumatized,” said Georgia Williams, a witness. “We heard gunshots firing, just pop pop pop pop pop and my brother said ‘get on the ground.'”

Monalisa Powell-Folkes added the gunshots sounded like “firecrackers.”
