We're learning that the 14-year-old accused of killing four people inside his Georgia high school was interviewed by the FBI last year in connection with alleged threats of a school shooting.  Meantime, a mom is speaking with Les Trent about texts her son sent her while the shots were being fired.  And it is an unthinkable medical mistake. A man went in for a spleen operation, and died after surgery. His family says it's because the surgeon removed his liver instead. Plus, you've heard the term needle in a haystack...well finding a three-year-old lost in a massive corn field is just as challenging. And the NFL season gets underway today with the reigning Super Bowl champs - the Kansas City Chiefs taking on the Baltimore Ravens. Taylor Swift will be there, and she's being credited with increasing the league's female fandom. As Ann Mercogliano reports, she's also boosting the number of ladies taking part in fantasy football.
