A 24yearold Iowa high school teacher arrested for allegedly having sexual relations with her 17yearold student is opening up about their trysts. Mary Beth Haglin, a substitute English teacher, showed Inside Edition the raunchy photos she sent to the student during their 6month relationship. Haglin turned herself in to authorities in July. Speaking to Inside Edition, she expressed remorse. "I never thought it would get this far," she said. #InsideEdition
