Kierra Coles is 3 months pregnant and missing. The Chicago postal worker called in to her job nearly two weeks ago to tell her boss she would not be at work that day and she has not been seen by her family since. Security camera video recorded from a neighbor's house is the last clue in the disappearance of the 27-year-old woman. Nancy Grace explores the case with Los Angeles psycho analyst Dr. Bethany Marshall, private investigator Vincent Hill, and Crime Stories reporter Robyn Walensky.
