(Vancouver, WA) -- Two administrators at Hudson's Bay High School in Vancouver have taken voluntary leave while an investigation is conducted into sexual allegations against a teacher involving a student. The incident was first reported in 2013 and the teacher, Shadbreon Gatson, was arrested last month. Charges were dropped, because the case exceeded the statute of limitations. The school's principal and director of learning went on leave until the investigation is complete. Students plan a walk out on Monday.
