Dunton brothers

The Dunton brothers are twins that live in Klamath and are brahmin rustlers. If you go to the Dunton home and wait till 6pm, they will leave for the bar which allows you to steal from their home without them catching you. Another option is to take Torrs quest to protect his brahmin, you will notice both Dutons to the northwest of the map that you are teleported to. You can kill them at this time without being attacked by the townspeople and after finishing the quest for Torr go and loot the house.

(Note: It could be considered cheating but if you steal from the brothers you can take their spiked knuckles. Then once you kill them, they will have another pair on their corpse)
