Overview

  • The FBI released a 398-page dossier in July 2025 detailing decades of investigative efforts into the 1971 DB Cooper hijacking.
  • Files show agents vetted and eliminated hundreds of suspects—ranging from a wheelchair-bound man to airline employees—by marking most leads as “eliminated.”
  • Court records in the files expose Donald Sylvester Murphy’s 1973 scheme to impersonate Cooper for a $30,000 extortion plot, which ended in his conviction.
  • Notable figures such as Richard McCoy Jr. are largely absent from the newly disclosed records, underscoring the case’s many ignored theories.
  • Independent analysts led by Eric Ulis are reexamining titanium fragments on a clip-on tie, tracing them to former metallurgist Vince Petersen for fresh scrutiny.
