The Tacoma News Tribune reports 37-year-old Kevin Gausepohl is charged with seven counts of communicating with a minor for immoral purposes and one count of obstructing a law enforcement officer.
Investigators say he told a Gig Harbor High School student he was conducting a study on how sexual arousal affects vocal ranges. The girl was 17 at the time. She was attending the school as part of the Running Start program that allows high schoolers to take college courses.
Other students told investigators they were also approached by Gausepohl, who resigned in October and denies the allegations.
