FORT WORTH, Texas (AP) – A former Fort Worth police officer has been booked in jail on a murder charge for the shooting of a woman through a window in her home.

Aaron Dean was booked on Monday afternoon. He also resigned from the police department, and the chief said he would have been fired if he didn’t quit.

Atatiana Jefferson was shot to death Saturday by Dean, who was responding to a report of an open door. Interim Police Chief Ed Kraus said Monday that there’s no indication the officers knocked on the front door, and that Jefferson died from a gunshot fired through a window accessible from the fenced-in back yard.
