A 31-year-old choir teacher is accused of performing oral sex on one of her 13-year-old male students.

Elizabeth Marie Moss is on leave from her job at Chestnut Oaks Middle School in Sumter, S.C. on Feb. 11. She was arrested and charged this week with criminal sexual conduct with a minor and contributing to the delinquency of a minor, according to the Sumter Item. Her lawyer disputes the charges.

"Our investigation has confirmed that (Moss) was in a sexual relationship with the student," Sumter County Sheriff Anthony Dennis said. "The school received the information first, then contacted us. The district's administration has cooperated fully with the investigation."

Authorities said the assault took place some time between March and April of last year. During a press conference, Dennis said the school became aware of Facebook messages Moss sent to the victim and other students that were "inappropriate," though not necessarily of a sexual nature.

Dennis also said the investigation is ongoing and more victims could emerge.

In a statement released to WBTW, Moss' attorney, Rose Mary Parham said, "These allegations arose after Beth disciplined some of her students at school. She is innocent of all charges and looks forward to her day in court."
