I don't know if this is relevant specifically to you, but a homeless man approached me in Port Authority in NY last Thursday and asked me how much a pair of tefillin were worth. When I attempted to dig deeper, he claimed that he had found "something" on the train and wanted to know what to do with them. I could not get him to actually show me any tefillin, but there definitely were what looked liked retzuos coming out of his bag. I tried to look and see where he was going, but he got suspicious and confronted me. The PA authority police said that they would keep an eye out for him, as this fell under the rubric of potential sale of stolen goods.
