I knew Major Mark Smith. Mark, perhaps as a result of his many wounds and time in captivity, was a few rounds short of a basic load. What Mark said on one day was not necessarily what he said several days later and he did not consider the discrepancies to matter.
I believe that his agents gave him the information that he paid for - it was what he wanted to hear and he believed it. I doubt that much, if any, of it was true, but it generated a cottage industry that drained the life savings of many MIA/POW families who were desperate to learn the fate of their loved ones. I don’t think that any of them survived the release of POWs in 1975 and most were dead within 24 hours of when they went missing.
