Sorry to post two replies, but what on earth do you mean, no signs of foul play? There's a ten year old, she goes to bed, in the morning she's gone, she doesn't turn up in an hour or two...is this not a sign of foul play? If you mean no sign of murder, that's one thing, but there has certainly been "play" and it has certainly been foul. I do not think foul play means just murder,or even violence, it means illegal activity.
