How do criminals launder marked bills?

Yeah, Robert Blevins is a novelist with no particular expertise, just one of hundred of self-styled Cooper experts who for the most part seem to have a fixation on the idea that Cooper survived his jump. It’s basically a conspiracy theory, grounded in the idea that anything said by the “mainstream” must be wrong. You can see from Blevins’ blog what his other interest is, which should tell you something:

Covering the people, facts, and events on D.B. Cooper and UFO lore since 2015.

Since Cooper was an unidentifiable falling object that night I suppose Blevins could have shortened his tagline to just

    Covering the people, facts, and events on D.B. Cooper and UFO lore since 2015.

:grin:

That’s about laundering drug money, not marked/recorded ransom money. Mostly irrelevant to the OP.

Good find. So according that that, the search only lasted a few months and then banks, casinos and the Federal Reserve were no long searching for the bills.

IOW, as long as he waited a bit then it was all good and he just had to be careful to not do things like buy a Caddy with a suitcase of 20s, then it wouldn’t have beena problem.

Except the problem is that someone has to be looking for the recorded bills.

Back in college in the 80s, I briefly dated a teller and they didn’t do anything like money in and money out streams. When she was first working there, she had made a couple of mistakes and they had no idea where she had made the mistake.

According to an author trying to sell books with a strange conspiracy theory, instead of the actual Lead FBI agent on the case, who said the exact opposite.

If that paratrooper had been Cooper, he would have worn boots and better clothing. (and a rain jacket, wool sweater and walking shoes or boots would not have looked out of place in November in the PNW)
In Search and rescue we found a dude dressed better than Cooper who
was in the last stages of hypothermia. (well, they found him, I was just part of the team back at the park). The guy was wearing jeans, running shoes, a flannel shirt and a down vest, but had twisted his ankle, and was caught in a spring rain in NorCal- night time temps never got below 40.

Cooper was wearing dress loafers, light socks and a business suit. It was wet, snowing and the temp was 20 degrees with nasty wind. He couldnt have survived.

That is besides the OP, but does show that the “expert” author is totally wrong.

Great point.
