Not such a dignent death after all...
Jon Adiglio was one of the last few citizens of Vault 92 left alive and sane.
Instead of fighting in the corridors, Adiglio locked himself in a closet and hid. 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.
His skeletal corpse appears in Fallout 3.
