New allegations have surfaced against a former Catholic elementary schoolteacher in Akron who quietly was sent to prison this year for sex offenses against a 12-year-old student.The accusations are contained in a lawsuit filed Wednesday against the Catholic Charities Diocese of Cleveland, St. Mary’s School in Akron and former music teacher Richard Rudman.The family of the 12-year-old girl contend in their lawsuit that school officials turned a blind eye to Rudman’s actions in the classroom, including his taking the student and others out of class under the guise of “helping him” with special projects.The suit also contends that Rudman “groomed, sexually abused, violated, molested and manipulated” the girl at school and away from the classroom.
