Sarah Kopp was a talented 15-year-old student when a charismatic sports teacher, 31-year-old Paul Grealy, arrived at her school and upended her life. It was a textbook case of grooming — the compliments that made Sarah feel "special", the accidental touches, then the regular sexual interactions. But it didn't end there. Sarah married and had a family with her former teacher. Which is what makes her fight for justice, 20 years later, that much more remarkable.
