This unnamed vampire was a member of Starr's nest.
At some unknown point in time this man became a vampire and a member of Starr's nest. Len Cuse was originally the leader of the nest but left it after he developed a conscience. Len later became the sheriff of Hibbing. For an unknown amount of time Starr and her nest looked for Len hoping to make him rejoin the nest. This vampire adopted Len's philosophy of using every part of the humans they kill, and to not just drink their blood. This vampire's nest consisted of three members: himself, Starr, and Catfish.
After spotting Len's photo in a newspaper, this vampire and his nest tracked Len down to Hibbing, Minnesota. Once they arrived in Hibbing they began killing several people. This drew the attention of hunter/sheriff Jody Mills, who realized the deaths weren't by animals, and she called for Sam and Dean Winchester for assistance.
The group initially suspected Len was the culprit, but after stalking him to a barn, they were attacked by Starr and her nest, who tied them up, and ordered Len to kill them all, so he could rejoin the nest. Len refused and was decapitated by Starr.
Before Starr could harm her captives, Dean broke free of his restraints and grabbed the machete Starr dropped after killing Len. Dean killed Catfish first and then this vampire. Starr went after Dean only to be knocked to the ground by Jody. Starr turned on Jody but was decapitated by Donna Hanscum, who broke free from her restraints, killing her.
