Fort Worth, Texas, police officer Aaron Dean, who shot and killed Atatiana Jefferson, a 28-year-old black woman, in her home, was charged with murder Monday, the Fort Worth Police confirmed. Dean had resigned from his job hours earlier.

The big picture: Dean and another officer had been responding on Saturday to a neighbor's call that said Jefferson's front door was open. Jefferson was inside playing video games with her 8-year-old nephew.
