A Microscopic Metal Flake Could Finally Reveal DB Cooper's Identity

"The famed and mysterious disappearance of D.B. Cooper has puzzled investigators for over half a century," writes a Seattle TV station.
Now new evidence is coming to light in the supposed "skyjacking," after a microscopic piece of metal found on D. B. Cooper's tie could help reveal his true identity. "Considering the totality of all that has been uncovered in the last year with respect to DB Cooper's tie, I can say with a very high degree of certainty that DB Cooper worked for Crucible Steel," said independent investigator Eric Ulis.

"I would not be surprised at all if 2024 was the year we figure out who this guy was," lis told another local Seattle news station:

This particle is part stainless steel, part titanium... 18 months ago, Ulis used U.S. patents to trace three of these fragments from the same very tie to a specific plant in Pennsylvania, Crucible Steel. "Headquartered in the suburbs of Pittsburgh, a significant subcontractor all throughout the 1960s," said Ulis. "It supplied the lion's share of titanium and stainless steel for Boeing's aircraft...."

Ulis claims evidence points to Cooper having in-depth knowledge of the 727 he hijacked, and of the Seattle area. Workers at Crucible Steel were known to travel and visit their contractor, Boeing. "This is also the time, 1971, when Boeing had this significant downturn, the big depression, with 'The last person leaving Seattle, please turn out the lights' [billboard sign]," said Ulis. "It's reasonable to deduce that D. B. Cooper may well have been part of that downturn."

Ulis admits his findings are not yet concrete. He's not crossing any suspects off the list. However, he believes from what he's seen, all roads lead to titanium research engineer Vince Peterson from Pittsburgh.
It all reminds me of that episode of Prison Break where they suspect one of the prisoner's is secretly D.B. Cooper...
