The unnamed Security guard was the first man who noticed David Hargrove, Emily Brandt and Corey Thompson were trapped inside the ATM. He tried to help them, but before he reached the ATM, he found the body of the local man who the killer killed before, and then he was beaten to death by with a crowbar taken from David's trunk. His body was dragged away by the killer, and placed on a seat. Later, David attempted to throw a Molotov cocktail at the hooded killer, only to realized that it was not the killer, but the body of the killed security guard.
