While I understand what you are saying,with her being a minor, if LE thinks she knows more than what she is saying, sensitivity to the girl is not important at this point. ET must be brought home at any cost,even if the minor must be put through the ringer to co-operate. Also,LE should put pressure on the parents to co-operate also. Now if they have tried this and she just still clams up,than not much they can do---at the moment.
This was what I was thinking.
