I just found the following post on the geocaching.com forums.

It would seem that Jeremy was able to get one of his bugs back after the 
cache that it was in was confiscated by the NPS.

Considering the caches that have been removed in the Tucson area had travel 
bugs in them, if one of them was yours you might want to try and get them back.
