Mark Lamia

Mark Lamia was one of the maintenance workers in Doom 3. According to the audio log on his PDA, he states that he is frustrated on his employees for their incompetency. He states that his employees constantly forget things and he has to keep an eye on them while they're working. He even manage to change the security lockers to 1-2-3, since he believed that was easy to remember, yet his employees forgot. It's likely that he had died from the demonic invasion.
