A man has been arrested on a murder charge after he shot & killed a 17-year-old who had been returning a BB gun to a Big 5 Sporting Goods. Aaron Brown Myers, 51, told police he thought the teen and his friends were about to rob a store and that he was also worried about the safety of his own 13-year-old son, who was in a jujitsu class next to the sporting goods store. Myers said he had a duty to act. #seattle #shooting #renton #kent #Big5 #localnews #security
