These unnamed hunters attacked the Alpha Vampire's house with Samuel Campbell.
Background[]
After discovering the location of the Alpha Vampire's hideout, Samuel Campbell led several members of the Campbell Family, including these hunters. They were preparing weapons to attack the house when they are first seen. They are seen coming with the Winchesters and the Campbells to try to capture the Alpha Vampire. While attacking the house, two of his hunters were killed by vampires. Later, Dean entered the courtyard of the Alpha Vampire's house to investigate gunshots and saw the bodies of these hunters. He then heard screams and saw a hunter being grabbed by a vampire and killed, blood spurting on the window from which she tried to escape.
