Bill of course they knew there was major thefts going on.
They caught the son by planting a large value gift card that was placed in a mail delivery truck that was being monitored by a hidden camera. They then were able to view the thief using the card at Walmart.
This lead to getting a search warrant and busting the whole family.
If you have any doubt about how bad the problem of theft is by some USPS employees just spend an evening on Google doing a little searching.
Its a huge problem.
