Nothing is known about Sabrina's life prior to or as the outbreak began.
Within the Holding, Sabrina retrieves a tray of freshly cooked egg quiche from the kitchen and proceeds to deliver it to the dining area when she gets distracted by the zombie shrine nearby. Riley approaches Sabrina and reminds her that the new arrivals are coming and will be hungry. She apologizes, stating that she was just trying to see what Teddy sees in the shrine. Riley asks if she has seen it yet, to which she declines but Riley assures that she will soon. She continues to the dining area while Riley goes to welcome the new arrivals.
Sabrina's fate remains unclear after the fire destroyed much of the Holding. It is possible she was among the cult members who became trapped in the underground parking garage and succumbed to the fire.
This list shows the victims Sabrina has killed:
- Possibly numerous counts of zombies and unnamed people
- This character is credited as Worker #1 in "The Holding".
