The FBI Released Bigfoot’s Official File

The episode details the surprising 1976–1977 investigation by the Federal Bureau of Investigation (FBI) into alleged Sasquatch hair samples. This examination was initiated after prominent Bigfoot researcher Peter Byrne carefully requested the analysis, leveraging a thin jurisdictional connection to potential fraud or crimes against federal property. Internal memos reveal that an assistant director reluctantly agreed to the one-time forensic testing to definitively identify the hair. Ultimately, the FBI crime lab report concluded that the submitted samples, which included hairs and tissue, “most closely resembles deer family hair.” This administrative file remained undisclosed for over four decades, only being released in 2019 following a broad Freedom of Information Act request, cementing the short-lived, anti-climactic Bigfoot file in American pop culture.
