Sandy Hook Elementary students leave on a school bus in Newtown, Conn., on Jan. 3, 2013. Students at the elementary school, where a gunman killed 20 students and six educators on Dec. 14, 2012, are returning to class at an alternative campus described by police as "the safest school in America." Survivors are set to finally restart their academic year in the nearby town of Monroe, where a disused middle school has been converted and renamed from its original Chalk Hill to Sandy Hook.
