What you must believe if you don’t believe in the Sierra Kills story. The Sierra Kills story says that two Bigfoots were shot and killed in California’s Sierra Nevada Mountains on October 8, 2010. It is known that afterwards, the man who shot the Bigfoots sent in a slice of hairy, human-looking thigh (the Bigfoot steak) to Ketchum’s DNA project. It is known that the thigh initially tested positive on MtDNA as “100% human.” Later rumors said that the thigh had tested as Bigfoot on nuclear DNA via eight separate labs.
A very large number of people, Bigfoot believers and skeptics both, think that the story is utterly ridiculous. Let us leave aside the rumors about nuclear DNA for a moment. It’s well known that Ketchum herself told observers that the thigh tested 100% human on MtDNA.
