A 24-year-old Iowa high school teacher arrested for allegedly having sexual relations with her 17-year-old 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 6-month 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.
