With monotonous regularity, cases crop up in the USA of children who were not at school and are subsequently killed by their parents or carers. Many of these deaths have similar features. Apart from non-attendance at school, there is the fact that the children are usually black, often fostered or adopted and the adults looking after them are very frequently religious maniacs. A quick trawl through the internet will throw up any number of child homicides bearing two or more of these features.
There are signs that crimes of this sort are beginning to cross the Atlantic. Where America leads, we follow! The most famous such murder was of course that of Victoria Climbie. Here you had all the classic elements of such crimes. The child was black and not being sent to school, she was being informally fostered and, significantly, the woman caring for her, Marie-Therese Kourao, was devoutly religious. She always carried a Bible in the dock during her trial for murder. The Khyra Ishaq case had three of the warning signs; a child who was black and not attending school, combined with parents who were weirdly religious. Although it didn't ultimately end in death, the Eunice Spry affair fell into the same general pattern. There you had children who were not being sent to school and who were being fostered by a woman who was an enthusiastic member of a fringe religious group. In 2010, there was another death with three of these features; in addition to non-attendance at school and being a member of an ethnic minority, the mother in that case, Satpal Kauer Singh, was also pretty religious.
It strikes me that children who have more than two of the factors which I list above, might very well be at increased risk of abuse or death. Not going to school by itself may not be a risk factor, but combined with more than one of the things that I mention here, might be enough to indicate a child at hazard.
