AURORA, Colo. — It’s not your average use for tape. A mother in Aurora, Colorado says her second grader was upset after her teacher put tape on her mouth. The concerned parent says the educator put cellophane tape over the mouths of her 28 students while they were in a library. She told police it was meant as a joke, and the students asked her to do it. Authorities say they aren’t planning to file any charges but did take a report. The teacher may still have to answer to the school.
