Nothing is known about Marta's life before the outbreak began, except that she was a mechanic and served in the Iraq War.
As Qaletaqa shows Alicia around the Black Hat headquarters, he introduces Marta and José, who are working on the ranch's helicopter that was shot down.
Marta's fate and location are left unknown after the zombie horde overran the ranch, trapping the remaining residents in the underground pantry. If she did manage to make it into the pantry, Marta has been killed as no other survivors were rescued from the pantry besides Alicia, Ofelia, and Lee.
This list shows the victims Marta has killed:
- Possibly numerous counts of zombies
