FBI Releases Files on a 1970s 
Case Involving Bigfoot According to the newly released documents, the 
short investigation happened in the 1970s. At the time, the agency was sent a letter on the matter by Bigfoot enthusiast 
Peter Byrne. Byrne contacted the FBI after sending them 
samples of hair and skin that he
was unable to identify. In his letter, Byrne, the director of Oregon's 
Bigfoot Information Center and Exhibition, 
sought clarification on if tests had occurred 
regarding his findings. The agency wrote back, saying an examination of the hair and 
skin would take place. It added that the analysis would be 
done "in the interest of research 
and scientific inquiry."  The investigation ended in 1977, but the bigfoot myth remains alive and well 
in the U.S.
