Princess, this was truly a "dastardly deed", if in fact he did as he stated.
If this box is close enough to get to and you can check on it, perhaps
you should.
It's very possible that he was only trying get a reaction and the box is
still safe.

If not, this could explain why so many boxes come up missing.

Hope your fears are for naught.
