A Jeannette High School teacher was charged Friday for allegedly having a sexual relationship with a male student. Maria Chappell, 38, of Mt. Pleasant Township, accompanied by her attorney, Jeff Monzo, surrendered to authorities Friday afternoon. She is charged with having sexual contact with a student, corruption of minors and unlawful contact with a minor. An investigation began on March 17 after high school Principal Patricia Rozycki reported the teacher's alleged conduct to city police. Investigators allege that Chappell had sex with the student at the high school. The victim told investigators that he and Chappell had sex in her classroom and at a hotel, according to an affidavit of probable cause filed by Westmoreland County Detectives. Chappell worked as an English teacher in classes for ninth-, tenth- and 11th-graders, according to the school district's website. She taught a class called “ethically speaking” to ninth-graders, the site said.
