After you finished barricading the gas station, you decide to lock down the rest of the place as you open the doors to other rooms until you get to the "Supervisor's Office". You open the door and find Zombie Girl restrained within. At first you can't tell whether she is a Zombie or not but her pale skin and red eyes as well as her torn and ruined clothes suggest that she most likely is an undead. The restraints that hold her wrists are stainless metallic chains so she won't be able to break free without help.
