A team of researchers chosen by the federal officials in Seattle have come across new evidence in the mystery of D. B. Cooper.

The Citizen Sleuths are analysing particles emitted from the clip-on tie that Cooper left behind after he hijacked a Northwest Orient plane in November 1971.

Tom Kaye, the scientist of the group, told King 5 Friday that a powerful microscope is used in their research has found more than 100,000 particles on the JCPenny tie. He added that the group has tried to indicate where some of the particles, such as Cerium, Strontium, Sulphur and titanium, yet can come.

A place where the various elements were used was at Boeing for their high-tech Super Sonic Transport plane, which was developed in the 1960s and 1970s. Kaye says, the evidence would point to the Cooper, a contractor or a worker for Boeing, where he would have worn with a tie.

“The draw went with him in these production environments, for sure, so he was not one of the people that these (production machines). He was an engineer or a manager in one of the plants,” Kaye told King 5.

Kaye added that he is looking for help from the public in identifying where some of the particles on the band. The public can reach the researchers at the Citizen Sleuths website.

The FBI announced in July that it is no longer actively investigating the case, said that it was “thoroughly reviewed all credible leads” during her 45-year study and has redirected these funds to other priorities.

The FBI has investigated, as a man who himself Dan Cooper hijacked a Boeing 727 across the Northwest on Nov. 24, 1971. He Later jumped out of the back of the plane wearing a suit and a parachute after receiving $200,000 in ransom.

No sign of Cooper has arisen, although bundles of money, accompanied with serial numbers, were found in 1980.

The FBI says it has conducted searches, collected all the available evidence and interviewed all identified witnesses. It says that it is caused a huge number of tips, but none has resulted in the identification of the hijacker.
