I am not sure who watches Destination Truth but in the episode named the 'Bhutan Yeti' they were able to gather evidence of a hair sample that is NOT in any data base. This sample was tested in a reputable lab who actually thought it was yet another sample that would not pan out. The hair sample was primate, not human, since it was courser than a horse's tail. This is yet a great example and specimen towards proof.
I bought the episode from iTunes, as I did the whole series *grin*, but the one episode can be bought for $1.99.
Just something I wanted to share.
