Marcus Falcir

Marcus is Daniell's father, who entered the lab before he did, to find out what the government was up to... Marcus appears in Cop Simulator, a game created by Wintersoft Studios...

Finding Marcus
Marcus can be found by going into the security room, his dead body is slumped along the floor, with a bullet in his head...

A file can be found in Mind of the Crazed, that states the Marcus is the agent who kills Daniell, so it is unclear whether the file was wrong, or the corpse of Marcus is just a hallucination.

Controversy
It is unknown why Marcus killed himself, with the most likely choices being hunted by a tracker, being outnumbered by patients (there are bloody hand prints on the windows and floor) or by going insane...

With the latter being most likely... Although a Tracker can be heard in the area searching for stuff.
