While it is a small and unlikely reason, it's a succint explanation that can be used to explain away this entire clusterfuck of an incident. Doubly so putting the explanation with little wording to leave doubt should help the family get some level of normalcy. At least now they can point to an article in the BBC to explain when employers, coworkers, other parents, or staff at the school inevitably bring it up. It's not perfect but it's an easy explanation to put people's minds at ease and dissuade any notion of wrongdoing from this ridiculous incident which will undoubtedly follow them for at least the next decade or so if not the rest of their lives.
