Shaw was an elderly man who survived a wendigo attack in 1959.
In 1959, when Shaw was a child, he and his parents were staying at a cabin on Blackwater Ridge in Lost Creek, Colorado. One night, a wendigo entered and attacked the cabin, scarring Shaw and taking his parents as food. Shaw, however, survived and was eventually found, barely alive, and told his story about the wendigo but no one ever believed him.
In 2005, when the wendigo started killing again, Sam and Dean Winchester came to Mr. Shaw asking about the night the wendigo took his parents, and Shaw told the brothers about the attack and what little he knew about the wendigo.
- The actor who played Shaw, Donnelly Rhodes, also played Father Simon in the Season 8 episode Clip Show.
- While its not clear why Shaw survived, he mentioned he was sitting near the fire during the time of the attack, the wendigo's one weakness.
