Is a werewolf mutt who got murdered by the North American Werewolf Pack, he was seen in Bitten. He was a bitten werewolf, and was turned by Zachary Cain. He stalked, raped girls and killed one girl, he was broken out of a prison in Arizona. In Bitten (TV series) he is released after serving his sentence, and claiming to be rehabilitated.
Elena managed to follow him to a secluded spot, where she jumped him while he slept, and tied him down with the seatbelt of his car, and then slit his wrists. She offered to let him go (giving him a chance to save himself) if he sold out the location of the mutts, and he agreed.
However, because of his past crimes against children, Elena broke her promise and left Olson to bleed to death.
Bitten (TV Series)
He's still the same from the book, but with one added detail. He was Elena's former foster parent's neighbor who she put behind bars for abusing children. He kept rabbits in his back yard which he used to lure children, and abuse them in the coop.
