Mother of missing baby comes under fire by the press; Kali Rocha guest-stars -- In a "ripped-from-the-headlines" episode, overzealous reporter Cindy Marino (guest star Kali Rocha, “Grey’s Anatomy”) accuses new mother Laura Kozowloski (guest star Ashley Williams) on national television of kidnapping and trying to kill her baby. That's the last straw for the despondent woman, who promptly commits suicide. Although everyone is under suspicion, including the mother and her ex-husband, Mike (guest star Pablo Schreiber), the case takes an unusual emotional toll on Detective Stabler, who is drawn in by the mother and her past. The search for the baby Kendall seems to be at a dead end -- but DNA provides clues that help solve the case, and offer new questions for one of the detectives.

The men of Seattle Grace go on a camping trip together, Addison and Callie must team up to work on a patient, Meredith assists Sloan with a procedure unlike any she has experienced, and, suspicious of her recent actions at the hospital, Bailey confronts Cristina.
