FBI releases 'Bigfoot' files from 1970s, decades after 'credible' Northwest sighting

The FBI released documents on Wednesday regarding a 1976 investigation into the hairy mythical creature: Bigfoot. It involved legendary researcher Peter Byrne, 93, who says he still hasn't given up hope of proving the existence of Bigfoot.

From CBS News:

In 1976, federal investigators responded to a request by Peter Byrne, director of the Bigfoot Information Center and Exhibition, which was sponsored by the Academy of Applied Science in Boston, to analyze mysterious hairs attached to a piece of skin. After the "Washington Environmental Atlas" wrote in 1975 that the FBI had analyzed a scrap of hair and it "was found to belong to no known animal," Byrne asked whether the FBI had truly conducted this analysis. 

"Will you kindly, to set the record straight, once and for all, inform us if the FBI has examined hair which might be that of a Bigfoot; when this took place, if it did take place; what the results of the analysis were," Byrne wrote in an Aug. 26 letter.

"Please understand that our research here is serious. That this is a serious question that needs answering and that an examination of hair, or the opposite, by the FBI, does not in any way, as far as we are concerned, suggest that the FBI, is associated with our project or confirms in any way the possibility of the existence of the creature(s) known as Bigfoot," Byrne continued.
