I write crime fiction.  Looking at this incident for the basis of a story, I would see some enterprising criminal, knowing the name of the recycling company, finding a way to trace the trail forward to the name of the man who now has his $100,000 in cash back at home.  Then I would have the criminal, maybe along with one or two associates, go and get it.

Looking at this in real life, I would recommend putting the money in a bank safety deposit box, before a real-life criminal follows the same chain of reasoning as I did.
