One explanation is. the Ingrams were young semi-transient working class people with an unstable life-style, struggling economically during their younger years, people with lots of problems. I think that had been their history even prior to arriving at Vancouver. Brian apparently moved back to Arkansas in adulthood where I think the family originated. Brian has been more stable with strong church affiliations in adulthood.
I dont see anything unusual in this. Young people with few opportunities move around a lot and accumulate all the expected 'life experiences' until they get some kind of footing. I am sure the last thing they expected was notoriety of the Cooper-kind! It was probably the last thing some of them wanted or needed at the time. Look at Pat's sullen face during the FBI news interview compared to Harold talking like a nervous magpie. The whole thing was completely out of their control and totally unexpected. Pat was by far the most resilient and I have a lot of respect for her.
Don;t be too quick to judge these people or read things into their story -
Dwayne was a painter at U-Cart Concrete Systems, did he quit his job? get fired? his employer was supportive after the find.. they just left the area suddenly..
If it was planted it likely wasn't known by the rest of the family.
Why did they leave the Bar in two hours, why didn't they return to look for more, that would be human nature. Young people with few opportunities, struggling economically should be eager to find MORE buried cash..
Their behaviour seems inconsistent with human nature, that alone doesn't prove anything but it raises some serious questions. We know the ramifications if Dwayne did plant the money there..
remember, no diatoms found..
The lack of diatoms indicates that the bills were never exposed to the Columbia River water, or at least until the bundles and other bills/fragments had been covered by a "protective" coating of sand or other goo. While this argument can be used to support a plant theory, it also supports a theory that Cooper did not land in the Columbia River itself.
Kaye was unwilling to say the Cooper money had no diatoms - he just didn't see any that were obvious in the pieces of three bills he had to examine.
The FBI lab apparently did not look for diatoms in its examination of the bills sent them. There is nothing in their reports that I have seen that mentions diatoms ..
However, diatoms are so endemic to this region, you would think anything exposed to the environment would pick up its share of diatoms except in specific conditions. As I understand Tom's experiment his bills picked up diatoms when exposed to open water, well oxygenated. Does this mean the Cooper money was never exposed to open surface water or a zone in water where diatoms flourish? Diatom experts in Washington I consulted were very skeptical of Tom's report and wanted to see several bills for themselves. But sometimes (old) diatom skeletons are not readily visible - sometimes stains are needed to reveal them?
Several more anecdotes feed into this problem. (a) Cooper bills were examined by the FBI lab on several occasions. The lab typed the sediments found between the bills as 'consistent with river washed (round) sands like those found in the Columbia River'. But of course the money doesn't have to be "in the river", but just "exposed to Columbia River water", as near the water sufficient to be exposed to Columbia river sediments (which are everywhere in that area). No FBI lab report I am aware of mentions diatoms at all. (b) Palmer made an interesting comment when asked why the money/bills looked as good as they did and had survived 'on the beach'. Palmer answer was that 'upper active layer sand is sterile'. If the money had always been away from pools and regions where diatoms flourish, in a "sterile" environment, that might translate into little diatom exposure, which Kaye or anyone else would see as 'no evidence of diatoms'. But as Tom reports - all of this is speculation pending better more definite tests.
If it were to turn out that the Cooper money shows no diatoms at all while also yielding Columbia River (round) sands between the bills as well as other Columbia River water sediments, then some scenario of a rather specific nature has to explain those results, and that probably involves the history of the money since coming back to ground when Cooper had it.
We had arranged to have diatom and other testing done on Cooper money, but the owner of the money abruptly withdrew shutting the project down; much to the displeasure of a number of scholars and others involved who had volunteered to donate their resources to the project.
The fact that Tom's test bills showed diatoms so easily - as one would expect - while the Cooper bills did not show a similar result for Tom, is perplexing and could be because of the money's history between the time Cooper bailed and the Ingram's found the money 9 years later. Taken at face value it may mean the money was never in a diatom rich environment during this time. Only lab testing can clear this matter up.
