Kimberly Smith, 40, was shot to death in her Clinton, South Carolina home on March 10, 2017. A licensed practical nurse and mother, she had worked a night shift and was resting when the door was forced open. Her estranged husband, Clinton Anthony Smith, who had been separated from her for about four weeks after a dispute, entered the home.

Kimberly’s son and daughter were at a nearby house; the children heard gunfire, called 911, and saw Clinton Smith’s vehicle leave the scene. Responding officers found the front door had been kicked in and that Kimberly had been shot four times. Law enforcement later located Clinton Smith and he was arrested after a confession.

What details about the days leading up to the shooting or the separation might help explain what happened that night?
