MILWAUKEE (AP) — A 28-year-old Messmer High School teacher has been charged with sexually assaulting a child, after she was allegedly caught performing a sex act on a student in a parked car.

Megan Garland is a science teacher at Messmer. A statement released by the school last week says she was suspended.

According to the criminal complaint, a witness noticed a car was moving and its windows were steaming up Thursday in the parking lot of another school. When the witness opened the door, he saw Garland performing oral sex on the 14-year-old male student.

A message left at Garland's home was not immediately returned to The Associated Press on Tuesday. It was not clear if she had an attorney.
