Mrs. McBain was the wife of Sheriff McBain, and the sister of Beagle. She was murdered 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.
- The bodies of Mrs. McBain and her husband disappear after you restore peace to Primm.
- There is a script where her head blows off when the Courier enters the house.
Mrs. McBain's corpse only appears in Fallout: New Vegas.
