The Powder Gangers stole into town at night and murdered my sister and her husband, the sheriff, in bed, while I was sleeping in the office.”— Deputy Beagle
Sheriff McBain was the sheriff of Primm, killed by escaped convicts in 2281. The McBains' decapitated corpses can be found in their bed in a state of undress, suggesting they were killed in their sleep.
- His outfit is identical to that of Lucas Simms from Fallout 3, consisting of a sheriff's duster and sheriff's hat that can be found on the floor near his corpse. A cowboy repeater can also be found here.
- The bodies of sheriff McBain and his wife disappear after restoring peace to Primm.
- There is a script where his head blows off when the Courier enters the house.
McBain's corpse appears only in Fallout: New Vegas.
