Tijuana, Baja California
Nothing is known about this old woman's life before the outbreak, except that she lived in Tijuana, Baja California.
This woman is outside the infirmary taking care of the elderly and sick residents until she notices Nick wandering around and calls him over to help. She watches as Alejandro stops by to administer medicine to Oliviero.
Although not seen, it can be assumed she was among the La Colonia residents to head for the border. When the border militia opened fire on the La Colonia residents, she is assumed to be among in the people who flee back towards Tijuana. However, this woman was likely one of the many residents to be gunned down by the militiamen.
