Sorry to hear about this OP.
You any photos of the missing items? might be a good idea to show them if you have, that way any parents who's kids have come home with these items will have an idea then where they have come from
I hope they see it too Ozzypostie ... or their parents (if young people). They are not the standard type of items are they that go unnoticed ? Also, sure it will help your wife to share it with the local people. x
