It wasn't foul play. That’s what the widow of reporter Grant Wahl is saying today about her husband's sudden death while covering the World Cup. She's a doctor and says the coroner’s report revealed he died of an aortic aneurysm and nothing could have saved him. Might there have been warning signs? And could a gas station clerk's intuition help crack the case of the four murdered University of Idaho students? One month after the crime, she says she had a feeling to check the surveillance cameras where she worked...and sure enough there was a white Hyundai just like the one investigators had been looking for. It was 10 years ago today that twenty first-graders and six adults were slaughtered by a gunman with an AR-15 style rifle at Sandy Hook Elementary School in Connecticut. On this somber anniversary, we're taking a look back at how we covered one of the worst school shootings in U.S. history. And Ellen DeGeneres is paying tribute to the former DJ and executive producer from her TV show who took his life in a hotel room at the age of 40.
