Changes over time

Stable / recurrent

  • The archive's current audit rates the core chronology as strong across the source history.

Added later

  • Decades-later interviews may add detail but cannot overwrite the 1967 record.

Unresolved

  • Complete chronological registry of later Gimlin interviews
  • Pre-event logistics disputes
  • Film-subject identity

Corroboration & evidence

Named co-witness

Roger Patterson is a co-witness to the reported event; Patterson's testimony must be modeled as its own witness/source chain.

Separate evidence object

The surviving film is linked to the event but is not treated as proof of Gimlin's testimony or of a biological subject.

Documentary strengths

  • Very early post-event interview
  • Surviving film and press chronology create a rich documentary case context
  • Deep longitudinal source history

Limitations / controls

  • The film's subject identity remains disputed
  • Later memories span decades
  • Shared event context requires source-level independence controls

What would improve the record

  • Enter later Gimlin interviews chronologically
  • Build Patterson's witness/source chain separately
  • Continue film-evidence provenance and competing-hypothesis analysis
