Jacob L. Stemmons (Identification Number: 7545-99) was an analysis supervisor assigned to Specimen Analysis in Level 2 of the Delta Labs on Mars. He was one of the few UAC personnel to survive the initial demon invasion. He became trapped inside Maintenance Area 4, underneath the Stasis Control Junction, after checking to see if there was an issue with the circuit breakers there. Doomguy 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 contains a code for Storage Locker 213.
Storage Locker Update (11-13-2145)
We have recently changed the code on the storage locker near the stasis transfer control to: 3 7 1. Please be sure to annotate this on the Security Report for the local security detail.

RE: Power out!! (11-15-2145)
We are aware of the power problems in your area. Presently, we are dealing with several power issues throughout the entire Delta complex. It would be a great help if you would check some of the circuit breaker boxes in Maint-04 to determine if it is simply a breaker issue. Please file a report with the help desk and we will be out to your department as soon as possible.
The damn power has been fluctuating all week in the Specimen Transfer Area. These conditions make it extremely frustrating to work! Can you please send someone down here to check on the situation.
- Jacob's death is scripted, so you can't save him no matter how fast you are.
- Notably, you can "save" Stemmons if you do not enter the maintenance area.
