A text copy of D.B. Cooper Part 43 of 43-426, is now available. This is the interview of FBI geologist Chris Fiedler who conducted a sand analysis on the Ingram bills, shortly after the Ingrams turned in their bills, when the bills were still wet! This is the only detailed money analysis document known to date which details both sand analysis and fingerprint analysis, conducted by the FBI Laboratory on the Ingram bills.

FBI GEOLOGIST FAVORS WASHOUGAL RIVER LANDING FOR DB
By Myron Struck â States News Service â Washington
Did DB Cooper land in or near the Washougal River rather than the Lewis River?
In the personal opinion of the Chief FBI geologist who worked on the case, DB Cooper may have landed in the Washougal River, not near the Lewis River where it had been presumed that he came to Earth â before about $5800 in compressed wet and eroded money was found along the banks of the Columbia River in February 1980, upstream from the Lewis
The Washougal River scenario is the private view of geologist Chris Fiedler, who handled the soil analysis on the money, and not part of the agencyâs official report to the Seattle Field Office coordinating the investigation.
Still, it seems to be the only clue that might help the investigation the FBI was able to glean from a recent analysis of the bills in its Washington DC research area known as The Laboratory.
The official reports says little was found on the wad of money. The basis for the new information is Fiedlerâs research of the sand particles found among the bills and his discussions with federal geologists in the field. He has concluded that the ârange of sand particlesâ found among the bills is similar to sediment found along the Columbia and a number of its tributaries.
Fiedlerâs opinion has been disavowed firmly by his mineralogy division section chief.
âHe could have landed in the Columbia Riverâ, Fiedler said, âOr he could have come down in the Washougal River. The latter is where my training and instincts tell me is more likely, based on the data I have available.â
The sand tests involve little in the way or complicated equipment â only a simple microscope and some geological reference materials that document the characteristics of sand particles. Those found in the bills were rounded, worn, and considered to have been exposed to exceptional wear and tear. âWhat we didnât find is clay or other substances,â Fiedler said. âThese substances could have indicated the money originally had been buried in dirt.â
When the money was sent back to the laboratory for examination, most of the bills were compressed together, but a number could be distinguished easily. Field agents had determined that the serial numbers matched those of the $200,000 Cooper skyjacking money.
The money was also routed to the Laboratoryâs documents division, the lead division handling the case.
First, the money was dried out, using some 23-cent blotter, a pair of tweezers, some heat, and a careful hand. Individual bills were placed in cellophane envelopes and sent to the Latent Fingerprints Division. The sand particles associated with the bills were routed to the mineralogy section where Fiedler made his analysis.
The most impressive analysis was the use of a $36,000 experimental laser beam process to detect fingerprints. The process was created accidentally by Xerox of Canada. When it tried using laser beams to photocopy documents, fingerprints would show up on the paper, making the process unworkable. The substance the laser detects from fingertip contact is unknown The device, however, has been successfully used in detecting fingerprints that were not visible through conventional chemical and powder detection.
These conventional chemical tests were also applied to the DB Cooper money seeking grease or oil fingerprint stains and amino acid fingerprint signatures.
All four systems turned up nothing. The money had been exposed to the waters of the Columbia River too long. It was impossible to detect any fingerprint traces, even those of Brian Ingram, the eight year old boy who found the money on Tena Bar near Vancouver.
