A former elementary school teacher in eastern Pennsylvania has been charged with having sex with a 13-year-old student.

Police charged 39-year-old Melinda Trezise of Cressona on Friday with statutory sexual assault and other offenses. Police say the student told them he had sex with her more than a dozen times.

Trezise was a sixth-grade teacher in the North Schuylkill School District. She resigned in April, when the allegations first surfaced.

She turned herself in Friday to face charges and was released after posting $5,000 cash bail. She declined comment.

Trezise is married with three young children. Police say she left a note in her desk at school that said, "My mistakes have been many. ... I need help _ a lot of help."
