CENTENNIAL, Colo. (AP) — Arapahoe High School students in Colorado returned to class Tuesday for the first time since a fatal Dec. 13 shooting on campus, greeted by increased security and signs on each of their lockers telling them they are loved and valued.
Students hugged one another, laughed, and gathered to talk. Some students discussed the ramped up security inside of the school. Others talked about whether they would take final exams made optional by administrators.
