One of the top administrators at a northeast Iowa high school is jailed on sex and drug charges. Authorities say 39-year-old Shane Oswald, an assistant principal at Hempstead High in Dubuque, is being held in the Dubuque County Jail on a $50,000 bond.

Oswald is charged with sexual exploitation by a school employee, distribution of a controlled substance to a minor and providing alcohol to someone under 21. Reports say there was a single victim who was a Hempstead student though it’s not clear if she’s still enrolled. Oswald has been on paid administrative nearly two weeks.
