Confusion and anger in Lansing, Michigan today where people are trying to make sense of the deadly shooting at Michigan State University. Three students were killed and five severely wounded when a gunman opened fire. As Steven Fabian reports, the student body was put on lockdown with an emergency text to run hide and fight. And it's been a mystery for more than three months - who won the biggest Powerball jackpot in history? Well, now we have the answer to the two billion dollar question. Plus, it's a key question in the murders of four University of Idaho students. Why did a surviving roommate never call 911? There may now be an explanation.
