LAS VEGAS (AP) - A Las Vegas high school teacher who recently won his job back in arbitration after he was fired several years ago has been suspended. The Las Vegas Review-Journal reports 54-year-old John Mannion was sent home from Bonanza High School on Friday after officials learned he faces felony drug trafficking charges. He was arrested last July on suspicion of selling the prescription painkiller Oxycontin to an undercover detective.
