A man driving a dead woman's car shot a police officer, then opened fire in a parking lot and a mall, authorities said. By the end of the day, four people, including the gunman, were dead. Police shot the gunman to death Sunday outside a Target store inside Ward Parkway Center in south Kansas City, police spokesman Tony Sanders said. Target employee Cassie Bradshaw, 19, was in a break room with two other people when they heard shots. Then, her co-workers saw a man in his 50s with a rifle "shooting everywhere," she said. "It sounded like maybe firecrackers at first but then they got louder and louder and louder, and it sounded like someone shooting a gun," she said.
