Postal workers drinking on the job and then driving off in their postal trucks.

It's a big investigation we broke last night.

And now we've learned that one of the men in our piece is no longer working in Milwaukee.

He'e's been transferred.

We caught Tom the mailman in uniform, drinking in the middle of the afternoon.

We also saw Tom then getting into his two ton mail truck and driving off.

And Tom wasn't too thrilled when we asked him about what our hidden cameras caught him doing.

John: "And you stop and drink and then you get back in and drive it some more?

Tom: "No. No."

John: "We have video of you drinking. Are you going to tell me that's not true?"

Tom: "Yeah I am."

John: "That's not you drinking mixed drinks at Mike's on State?"

Tom: "No. You got me drinking mixed drinks at Mike's on State?"

John: "Aboslutely. Yes."

Tom: "I dont believe you."

We shared our video with Milwaukee postmaster Bob Cavinder who promised a quick and thorough investigation. "We need to look at what's happening out there withour employees and make sure theyre staying on their route," he told us.

Now we've learned that postmaster Cavinder's route has taken him right out of Milwaukee.

He has been transferred to St. Louis.

And it's unclear how the transfer will impact the investigation into the men we discovered drinking, driving, and delivering the mail.
