OLEAN, N.Y. — Charges against Olean High School Principal Jeffrey Andreano were dismissed with prejudice Tuesday in Olean City Court, ending a case tied to an alleged incident involving a student in December. Andreano was arrested Dec. 12 by Olean police and charged with endangering the welfare of a child, a misdemeanor, and second-degree harassment, a violation. The judge dismissed both charges after finding they were unsupported by evidence, according to Andreano’s attorney, Barry Covert.
