SEATTLE (AP) — Bullets recovered from two bystanders killed during a shootout at a Seattle festival last weekend do not appear to have come from the gun that a 15-year-old arrested at the scene was firing, police said in court documents filed Wednesday. In a statement supporting the charges, police said the teen was seen firing an untraceable ghost gun into a crowd, but preliminary testing of bullets recovered from two bystanders killed showed they did not match that weapon. Shell casings found at the scene of Sunday’s shooting indicate four weapons were fired during the shootout. Police say a 19-year-old suspect involved in the shooting was shot and killed at the scene. The statement did not indicate who might have fired the bullets that killed the bystanders.
