The Elevator Guard (portrayed by Patrick Sabongui) is a Security Force member.
He was ordered to kill Marty first and then Dana if she didn't cooperate. During his confrontation with Dana and Marty, he gets startled by Judah Buckner's severed arm on the floor and gets distracted long enough for Marty to attack the guard and leave him unconscious. He is last scene laying down on the floor of the elevator with the severed arm pecking at his face. His death is not shown to us.
