The DNA study is summarized in Scott Carpenter's book, Truth Denied. The sample collection itself was quite interesting. You can collect DNA from human hair, but not, as it turns out, from bigfoot hair. You need the skin tag from the root of the hair to extract the DNA. The most effective collection method was to smear bacon grease around the trunk of a tree 10-12 feet up, and then wrapping the trunk underneath with several turns of packing tape, sticky-side out. Other samples came from various parts of the country, hairs stuck on barbed wire, etc.

One of the samples was from a juvenile that was killed by a hunter near Dixie Valley, CA.
