Sandy Hook students, teachers head back to school Thursday

Tom Fico held hands with his son Lucas, 5, as they jump-skipped on their way to kindergarten, after dropping off his older brother Jake at the Theodore Roosevelt School in Burbank, Calif., early Monday. Teachers, parents and students are making an anxious return to school this week after a gunman stormed into Sandy Hook Elementary School in Newtown, Conn., shooting to death 26 people before killing himself.
