College campuses have increasingly become crime scenes with rampant drug arrests, sexual assaults, and too many massacres of innocent students.

Crime On Campus explores three recent stories that spotlight this disturbing trend: at San Diego State, one girl's death from a drug overdose triggered a campus-wide crackdown that resulted in scores of arrests. At Berkeley, the rape of a student by a college football player illustrates the need for better reporting of sexual assault on campuses across the country. And finally, the family of one of the victims of the shooting rampage at Northern Illinois University recounts the last moments of their daughter's life, as we try to understand what could have driven a young man to commit this horrific attack.
