POTTSTOWN, Pa. — A former Pennsylvania high school teacher has pleaded guilty to having sex with a 16-year-old student.

Investigators say 38-year-old Melissa Bonkoski started communicating outside of class with a male student who was in her science class during his freshman year. They allege she kissed him multiple times in her car and assaulted him at her home in 2016. An investigation began when the victim’s girlfriend discovered texts from Bonkoski.

Bonkoski was a teacher and coach at Owen J. Roberts High School in Pottstown.

The Reading Eagle reports that Bonkoski pleaded guilty Monday to charges of institutional sexual assault, unlawful contact with a minor and corruption of minors. She remains free on bail pending sentencing.
