Two boys, ages 7 and 11, are accused of trying to rob a woman with a loaded gun, police said Sunday. The boys tried to carjack a 22-year-old woman who was in her family's truck waiting for her parents in a church parking lot, Portland police said in a statement. Ami Garrett, of southeast Portland, told officers that when the boys approached her, the younger boy told the older boy to "show her your piece."
