When there's a medical emergency on a plane the crew usually asks if there's a doctor on board. During a flight over the weekend, it was TV's Dr. Oz who stepped in. He told Ann Mercogliano what happened. And she's the mother of five who went hiking last summer in Maryland and never came back. Later Rachel Morin's body was found near the trail. Now a suspect's been arrested and the victim's grieving mother says she is relieved to see justice for her daughter. Plus, it's been seven and a half years since Sherri Papini faked her own kidnapping. She did time in prison, ended up divorced and lost custody of her children to her now ex-husband. He's never spoken publicly about his ordeal...until now. His interview comes as we learn his ex-wife is claiming she's writing children's books. And she's got quite the social media after being dubbed the world's hottest scientist...now she's making headlines because she's been diagnosed with dengue fever. She didn’t get it here…but there are a few cases of dengue fever being contracted in this country.
