SEATTLE (AP) — Preliminary testing showed the bullets that killed two bystanders during a shootout at a crowded Seattle food festival last weekend didn’t come from the gun a 15-year-old arrested at the scene was seen firing, police said in court documents filed Wednesday. In a statement supporting the charges, police said preliminary testing of bullets recovered from the two bystanders killed showed they did not match that weapon. The shooting in the waning hours of the Bite of Seattle festival near the Space Needle left three people dead, including a 19-year-old suspect, and at least four bystanders injured, including a toddler. It isn’t clear which weapon or weapons fired the bullets that hit the festival attendees. The witness saw a man in a light blue top who started running; the witness believed that was where the first shots came from.
