The former Fort Worth officer involved in the fatal shooting of a woman in her own home Saturday night has been charged with murder. Aaron Dean had resigned earlier Monday morning before he was taken into custody and booked into the Tarrant County Jail. He fatally shot 28-year-old Atatiana Jefferson while she and her eight-year-old nephew were playing video games. Fort Worth mayor Betsy Price has promised there will be a fully transparent investigation of what happened.
