Private investigator Eric Ulis has potentially uncovered a major new clue in the infamous 1971 D.B. Cooper skyjacking case. A microscopic metal fragment found on Cooper’s tie matches materials used by aerospace parts supplier Crucible Steel. The titanium and stainless steel particle likely came from the company’s Pennsylvania factory which provided Boeing aircraft components.
Ulis believes this links Cooper to aviation industry knowledge. Evidence suggests Cooper knew intricate details about the hijacked Boeing 727 model and Seattle area where Boeing was struggling financially at the time.
By tracing 3 similar microscopic particles on Cooper’s tie to Crucible Steel, investigators can now connect dots to the company’s employees. Ulis reveals titanium engineer Vince Peterson as a compelling person of interest who worked for Crucible, traveled to Seattle, and fits some details of Cooper. Though not definitive yet in revealing Cooper’s true identity after 52 years, Ulis argues the breadcrumbs point to 2024 finally cracking the mysterious case.
