Carl Maynard

 is the chief engineer of Vault 92.

He and Parker Livingston are working on cleaning up a leaking signal corrupting the recording, though neither identifies it as the white noise. Maynard's logs reveal that an underground lake or spring has applied pressures to the buried walls of the vault until they have caved in, flooding the entire bottom level. It is through this breach that Mirelurks came to infest the vault.
