That's a great Snider song, too bad about him passing.

Richard McCoy Jr is your best suspect by about 5000%.

Quoted:
This was already known before, some speculation he worked as a machinist or similar in aerospace due to the metals found in the tie. Wait...aren't there aerospace companies in the area?!?! Er. Mah. Gerd.

Didn't read link or anything outside of this thread but assuming that is what it is...it's not new news.

That's where I'm at. Dan Gryder makes a very compelling case that it was him.

you better stop posting and start running

Or even better, bought a tie at a thrift shop with cash.

The guy's theory goes out the window if DB Cooper bought the tie at a thrift shop or garage sale.

To long did not watch....

studying the guys tie - tied him to a lab working on titanium metals...

Quoted:
I think it was McCoy or Ted Braden.  Braden was in MacVSog, deserted, and ended up being a career criminal.

FBI agents used several banks in the Seattle area to assemble the ransom. The money 10,000 unmarked twenty-dollar bills, most of which had serial numbers beginning with "L" (indicating issuance by the Federal Reserve Bank of San Francisco) was photographed on microfilm by the FBI.

The FBI speculates Cooper did not survive his jump, for several reasons: the inclement weather on the night of the hijacking; Cooper's lack of proper skydiving equipment; his drop zone was a heavily wooded area; Cooper's apparent lack of detailed knowledge of his landing area; and the disappearance of the remaining ransom money, suggesting it was never spent.

Using fixed-wing aircraft and helicopters from the Oregon Army National Guard, the FBI coordinated an aerial search along the entire flight path (known as Victor 23 in U.S. aviation terminology but "Vector 23" in most Cooper literature) from Seattle to Reno. Although numerous broken treetops and several pieces of plastic and other objects resembling parachute canopies were sighted and investigated, nothing relevant to the hijacking was found.

On February 10, 1980, eight-year-old Brian Ingram was vacationing with his family on the Columbia River at a beachfront known as Tina (or Tena) Bar, about 9 miles (14 km) downstream from Vancouver, Washington, and 20 miles (32 km) southwest of Ariel. He uncovered three packets of the ransom cash totaling around $5,800 as he raked the sandy riverbank to build a campfire. The bills had disintegrated from lengthy exposure to the elements, but were still bundled in rubber bands. FBI technicians confirmed that the money was indeed a portion of the ransom: two packets of 100 twenty-dollar bills each, and a third packet of 90, all arranged in the same order as when given to Cooper.

The discovery launched several new rounds of conjecture and ultimately raised more questions than it answered. Initial statements by investigators and scientific consultants were founded on the assumption the bundled bills washed freely into the Columbia River from one of its many connecting tributaries. An Army Corps of Engineers hydrologist noted the bills had disintegrated in a "rounded" fashion and were "matted together", indicating they "had been deposited by river action", as opposed to having been deliberately buried. That conclusion, if correct, supported the opinion that Cooper had not landed near Lake Merwin nor any tributary of the Lewis River, which feeds into the Columbia well downstream from Tina Bar. It also lent credence to supplemental speculation the drop zone was near the Washougal River, which merges with the Columbia upstream from the discovery site.


The "free-floating" hypothesis presented difficulties; it did not explain the ten bills missing from one packet, nor was there a logical reason the three packets would have remained together after separating from the rest of the money. Physical evidence was incompatible with geological evidence: Himmelsbach wrote free-floating bundles would have washed up on the bank "within a couple of years" of the hijacking; otherwise the rubber bands would have long since deteriorated. Geological evidence suggested the bills arrived at Tina Bar after 1974, the year of a Corps of Engineers dredging operation on that stretch of the river. Geologist Leonard Palmer of Portland State University found two distinct layers of sand and sediment between the clay deposited on the riverbank by the dredge and the sand layer in which the bills were buried, indicating that the bills arrived long after dredging had been completed.


In late 2020, analysis of diatoms found on the bills suggests the bundles found at Tina Bar were not submerged in the river or buried dry at the time of the hijacking in November 1971. Only diatoms that bloom during springtime were found, placing the date range that the money entered the water at least several months after the hijacking.


In 1986, after protracted negotiations, the recovered bills were divided equally between Ingram and Northwest Orient's insurer Royal Globe Insurance; the FBI retained fourteen examples as evidence. Ingram sold fifteen of his bills at auction in 2008 for about $37,000. The Columbia River ransom money remains the only confirmed physical evidence from the hijacking found outside the aircraft.

This theory should be easily proven or disproven by the process of elimination.

Quoted:



They wondered how the packs of bills moved and got deposited together?  They were frozen in a block of ice at one point and floated to that point.   The rubber bands failing were moot when it was a block of frozen bills.  Explains the tumbled rounded edges of the packs while the main surface area remained intact.

Ice doesn't float down the Columbia river.
