I am currently helping to homeschool my granddaughter, after persistent bullying at school, and I know that the home educating community was immediately aware that the death of this poor little girl would result in people attacking the idea of home education.
It is likely that this little one was withdrawn from school because she had signs of injury, and we can't be sure that it hasn't happened in a few previous cases, given that there are so many child murders in the UK -about one per week. However, I would like to make a couple of points.
Sara's injuries were visible when she was at school. Not only to the staff, as other children had previously told their parents about them. So the abuse had already been noticed before she was withdrawn. It was not a case of nobody knowing, but this did not save her life.
If an issue has been raised with Social Services, the fact that a child has been deregistered from school makes no difference. They still have the power - and, of course, the duty - to investigate. Whether a child is at school or not, social workers should be investigating and interviewing the parents. It may be that the parents made sure that they were always out when the social workers called, but they would hardly be the only ones to try this dodge. In previous cases of child abuse leading to murder, it usually turns out that the parents have been avoiding social workers for months, even though their kids are at school. Others have manipulated their social workers into accepting fabricated stories about their child's welfare.
Home education does not prevent the authorities from doing their duty, nor does school attendance ensure that it will be done. In practically all cases of the murder of school age children, the victim has been at school. The abuse has usually gone on for months, or even years, despite the fact that the child has been attending school. Admittedly the attendance is sometimes irregular, but they have nearly always been to school, been seen by neighbours, and have not been hidden from sight. But this has not prevented their murder.
Over the years, there have been so many terrible cases and so many calls for greater protection of vulnerable children, and yet the cruelty continues. Maybe part of the answer involves more funding for social services. Maybe we also need greater rights for grandparents, to see their grandkids more regularly and not be afraid that, if they report concerns, they will be prevented from ever seeing them again. A watchful granny would not have saved poor Sara, whose relatives were far away in Poland and Pakistan, but other kids might be saved in future.
