Alerted by early-morning noises in his Oklahoma City, Okla., residence, off-duty policeman Steve Pistole got his .357 Mag. service revolver and checked his daughter's bedroom. He found a man clad only in a shirt and socks on the 9-year-old girl's bed. Firing several times, Pistole killed the intruder. The officer's daughter was treated for bruises to the head suffered during the attack.
