Jon Adiglio

 was one of the last few citizens of Vault 92 left alive and sane.

Background
Instead of fighting in the corridors, Adiglio locked himself in a closet and hides. While there, he wrote a note to his wife and children telling them that he had died with dignity and not gone insane. He then killed himself with a laser pistol.

Appearances
His skeletal corpse appears in Fallout 3.
