Meredith Powell, a 24-year old math teacher at Lincoln High School in Tacoma, is accused of seriously inappropriate behavior with two students.
According to court document obtained by KIRO, Powell allegedly gave a blow job to a 15-year old student and had "sexual contact" with a 16-year old… all while the rest of the school was attending an assembly last month.
The alleged incidents took place in Powell's classroom, giving a whole new meaning to The Pythagorean Theorem.
Powell pleaded not guilty on Friday to counts of third-degree child rape, along with one count of communication with a minor for immoral purposes.
The latter charge was based on Powell supposedly sending one of her students a nude picture of herself in a bathtub via Snapchat.
Tacoma police became privy to Powell's actions after she wrote a letter to one boy’s girlfriend apologizing for “promiscuous” and “unprofessional” drunken text messages she exchanged with one of the boys.
