The kind of person who would abduct a child like this may well have spent time watching the area and quite possibly a specific child or group of children. They could have been monitoring the times the children were out, waiting for the opportunity to act. It's the kind of thing you just can't factor in.
Of course all parents are cautious about their child's safety, but it really depends on the environment doesn't it? Playing out at this age may well be perfectly normal in such a small village. It's not something I would let my 4 yo do, but I live on a busy road where children don't generally play out.
Like everyone, I hope she is found swiftly and safe.
