A fourth high school student has come forward claiming 24-year-old former math teacher Meredith Powell sexually abused him during her time at Washington's Lincoln High School. Powell was arrested in February and then confessed to performing sex acts with multiple students, one as young as 15 years old, inside her locked classroom, as well as sending them sexualized pictures of herself. She previously faced two counts of child rape and one count of communication with a minor for immoral purposes.
