Sorry, no lilac, she won't have been taken to be brought up by someone else. She's too old for that as she can talk and has a memory. If they were targeting a youngster for that they would take a baby, and remember there were was a younger girl in the room.
A retired policeman on Sky explained last night that the room wasn't locked or broken into. It seems the little girl woke and wandered out. The dogs traced her scent to a local supermarket where it disappears. That points to an opportunist, which is why it is most likely local and the idea that she was spirited out of the country in hours is unlikely.
