Peter Stevens

Peter Stevens was a resident and technician of Vault 87.

The player can locate a computer terminal with his private logs in the Vault, just inside the entrance of the Reactor Room if the player came from the Terminal-locked door in Little Lamplight. Peter apparently lost his son Jason, and the children's laughter he kept hearing caused him to go mad with grief. Unknown to him, he was not hallucinating the children, but probably hearing the kids in the Little Lamplight Caverns.

Upon searching further into the Vault, one can find a medical terminal that lists "Jason Stevens" as deceased under an 'unexplained' death. On the same terminal, it notes that the unexplained and undefined deaths were related to the EEP, or FEV experiment, program.

Terminal Logs
Many of the data files are corrupted, and therefore, a number of the logs cannot be read. There are some, however, that survived time. They are Journal entries 06A02, 06A05, and 06A07.

Cut content
Cut content designed to be on the Vault 87 Overseer's terminal claims Peter was never married, and never even had a child, and seem to express that he was simply going mad, though the cause is unknown. However, it should be noted that this content is was removed from the game's final build, and therefore may or may not be canon. The note says:
