Demian Linn is a researcher working in Psychotronics. In one of the emails he states that he manages to leave his Morgue keycard inside the Morgue and asks Annalise Gallegos for help.
Linn and his colleague Rory Manion tried to made several hypothesis about the Mimics' ability to transform into still objects. Linn, dissatisfied with more rational explanations, tried to believe that Mimics used some kind of magic to do so.
During the Typhon outbreak, Linn seals himself up inside the Psychatronics Material Extraction lab armory. He later contacts Manion asking how he's holding up. The two then decide to escape to Arboretum through G.U.T.S..
