It has been three weeks since Escondido teen Amber Dubois was last seen, and now a $60,000 reward is being offered for information about her disappearance.

Nationally known missing children advocate Marc Klass, whose daughter was kidnapped and murdered in 1993, announced the reward offering Wednesday outside Escondido High.

Dubois, 14, was last seen walking outside Escondido High School. Anyone with information regarding her disappearance is asked to call (760) 743-8477.
