There is now a $50,000 reward being offered for information that leads to the arrest of whoever is behind some recent mail carrier robberies here in Connecticut. The U.S. Postal Service says mail carriers were robbed in a half-dozen Connecticut cities and towns over the past few months. Apparently, the thieves have been targeting postal workers for the keys that open mail boxes. The US Postal Inspection Service announced the reward offer, but not a lot of other details, citing the ongoing investigation.
