The chaos began with police finding an elderly woman dead and her car missing. It ended when officers fatally shot the man driving the car — but only after he fired on a police officer and later people at a shopping center, killing two of them. Police trying to make sense of the four deaths were reviewing security footage and interviewing hundreds of witnesses to the shooting Sunday outside a Target store inside Ward Parkway Center in south Kansas City, police spokesman Tony Sanders was quoted as saying by the Associated Press.
