JACKSONVILLE, FL — Three First Coast students are facing criminal charges after a teacher says they were involved in oral sex in the classroom.

Christopher Lemay, 18, [pictured] is accused of paying a 16-year-old-girl to perform the act on another boy at Sandalwood High. Those two are under-age, so First Coast News is not releasing their identities.

Sandalwood administrators say the act happened under a table in a large class full of students, so the teacher had limited visibility.

The news is catching even veteran educators by surprise.

“It is not indicative of any school in Duval County,” said Acting Principal Jack Shanklin.

“I’ve been in education a long time and I have never seen a situation like this in any educational setting,” he said.

All three students have been assigned to alternative schools.
