1x5 - 911: Did the Killer Call?

After a man's savage murder at home, his wife is in the frame after calling 911, but the truth is more macabre than anyone dared believe. Also, a husband finds his wife with shots to the head. He claims it was suicide-the police have their doubts. Also, a woman called her husband saying she was shot by an intruder in their home; he picked her up and called 911 while rushing her to the hospital.
