'There's a lot that has to get fixed': Atatiana Jefferson's brother

Aaron Dean, the officer who shot Atatiana Jefferson, resigned on Monday before he was fired for breaching a string of police policies in shooting Jefferson dead, according to Fort Worth Police Chief Ed Kraus.

Jefferson's death brought outraged calls for an investigation into Fort Worth Police, whose officers are accused by her family's lawyer, Lee Merritt, of fatally shooting seven people in under six months.

Jefferson's family has called for the swift prosecution of Dean, who was arrested on Monday and posted bond overnight.
