Maria is a single mother, devoted to her son Sean. She is separated from Sean's father,Ian, but Ian had regular access to his son.
When Sean was four-and-a-half, Maria was becoming concerned at his increasing reluctance to see his father. Ian appeared devoted to Sean, and there seemed to be no problems. But finally, the situation became so bad that she managed to extract from Sean his "secret" (he had been told that his mother would die if he told anyone what was happening). Ian had been systematically sexually abusing Sean - in a swimming pool, so that all the evidence was immediately destroyed.
Maria was totally distraught, and sought help. Everyone blelieved Sean; his teacher, his GP, social workers, his family. The experiences he described were far too graphic to have been invented by so young a child. But - and here was the biggest problem of all - because of his young age, his evidence could not be accepted in a court of law. The physical damage to Sean could, it was said, have been caused by constipation. Ian remained free and at large.
Eventually, Maria was introduced to a family courts lawyer, who said she MUST pursue the matter through the family courts. This she did. The judge believed Sean, and a restraining order was imposed on Ian, preventing him from going anywhere near his son. When, a year later, the civil courts finally decided to take action, Ian's computer was clean (after all, he'd had a long time in which to see to that), and any other evidence was long gone.
Sean is now eight, and is finally beginning to be able to put some of his trauma behind him. Time will tell how much lasting damage has been inflicted upon him, but he has a close and happy relationship with his mother - who is still very traumatised at what happened to her son - and his extended family.
The last I heard of Ian was that he had a new girlfriend. With young children.
