Independant DNA Analysis of Smeja "Steak" From Sierra Kills

From this it seems definite that the same sample analysed had two sets of mitochondrial DNA, one human of presumably European ancestry and the other female black bear, with the bear DNA predominant and the sex of the human DNA donor not determined, but most likely from more than one human donor because parts of the sequences do not match up between tested samples.

I would definitely go for contamination in this case. And as one commentator has noted, there is no way to know for certain that this steak came from whatever it was Justin had shot at, it was found later when Smeja and others went back to look for remains after he had left the bodies in the first place. But one thing is certain, the sample does NOT represent a crossbreeding of a human and a bear!
