Jacob Stemmons

Jacob L. Stemmons was an Analysis Supervisor assigned to Delta Labs, Level 2 on Mars during the events of Doom 3. He was one of the few people to survive the first wave of the demonic invasion. At some point, he became trapped inside a Maintenance Area underneath the Stasis Control Junction. The Nameless Marine overheard Jacob's calls for help and tried to free him. Unfortunately, an Imp got to Jacob first. The Marine killed the Imp but could not save Jacob.

Jacob's PDA reveals that the code for Storage Locker 213 is 3-7-1.
