Corpse to the right is Beru
Beru is corpse in the Nipton in 2281.
Located just in front of a ruined Nipton house, to the right of the town hall, there are two corpses. One looks to be a male human, while the other is female, lying next to each other. They look like they've been charred.
Looking at the burned corpses will reveal the male to be named "Owen" and the female "Beru".
Beru appears only in Fallout: New Vegas if the player has chosen the Wild Wasteland trait.
Behind the scenes
This is a cultural reference to the film Star Wars IV: A New Hope, where Luke Skywalker returns home to find it on fire and his aunt and uncle (whose names are "Owen" and "Beru) are found dead and burned.
