Sheriff A. Tyson is a sheriff stationed in Gunnison, Colorado.
Background[]
Tyson is the current sheriff of Gunnison, Colorado in 2016, a time when many locals began disappearing. She had been a sheriff for only two years and could not explain the disappearances. As the town was a small place, she mainly focused on calming down the citizens.
After the disappearance of Libby Strauss, who was not a local, Tyson was visited by Sam and Dean Winchester. Tyson revealed that a similar case occurred 27 years ago, but she had no theories of her own and offered the brothers free access to case files and the identity of the witnesses.
