PEEKSKILL, N.Y. (AP) — A schools superintendent in the Hudson Valley says several high-school seniors were given credit for a nonexistent course to help them graduate. He says the case is being turned over to the district attorney. Two weeks ago, Peekskill Superintendent James Willis said four guidance counselors were being reassigned while irregularities were investigated. Their names were not made public. In a letter dated Monday, Willis said problems were found in the transcripts of 34 seniors.
