I have not seen this segment in quite a long time. However I still wonder if there has ever been any kind of revelation as to just how much Mr. Morgan was involved with the Treasury Department. You will recall that he said his Treasury ID was missing after he had escaped from whoever it was that kidnapped him.
And what of the men who ransacked the Morgan home claiming to be from the FBI? Who were they? Who did they work for?
And has anyone ever figured out the meaning of the Hispanic names on the 2 dollar bill?
This case has always stuck with my mind!

I posted a few articles on this case a couple of weeks ago. Not sure if they were any help to you. To summarize Morgan may have had knowledge of not only money laundering but drug trafficking that was taking place at the time in Arizona within an organized crime syndicate. The original NBC broadcast of this segment goes into this a bit more than the syndication and it mentions that this same crime syndicate was suspected in the murder of another Arizona man: Don Bolles

It's possible that Morgan may have met a similar fate much like Don Devereux mentioned because he was involved with people that he probably shouldn't have been involved with to begin with. Whether he did this of his own accord or was prompted by the government to help investigate these people, that is just one of the many mysteries that needs to be sorted through in this case.

I've got a reply to a post on here somewhere... I listed the names and some other stuff that was found on that $2 bill to see if anyone could piece the clues together, but I don't think I got any responses.

One thing that was interesting is that each of the hispanic names was written in alphabetical order, A-H, iirc. It made me think that it was a code, rather than "naming names".

I found that thread and bumped it up.
