When Jess Martinez was just thirteen, she was sexually abused by her sister's much older boyfriend. No charges were brought at the time, but the impact it had on Jess's life was dramatic, causing lasting damage. Many years later, when Jess discovered her abuser had been jailed for another case of child abuse, she took the courageous decision to tell her own story, waiving her right to lifelong anonymity. Speaking to Dr Sian Williams, Jess describes the challenges of bringing an old case to court and praises the police and lawyers whose efforts provided her longed-for Life Changing moment.Producer; Tom Alban
