This article is littered with spoilers, so I reckon you might ought'a mosey on down the road if you don't want to read any plot details.
–Mrs. Fortuna to Miranda
At the beginning of the Luisa Fortuna mission "My Sister's Keeper", Marston sees her crying and being consoled by Miranda on the porch of Campo Mirada as the rest of the family collects their belongings to abandon the house. Judging by what her daughter Luisa says, she escaped to America to get away from the revolution and the violence from the government. It is unknown whether she returned to Mexico.
- When approaching Campo Mirada at the beginning of "My Sister's Keeper", before starting the mission, it is possible to kill her and her daugther on the front porch. It takes quite a lot of bullets to kill her, but standing close to her, and shooting her (Making a slight cut scene, where you shoot her in her stomach) she will die, (Same thing with her daugther). When looting her you'll receive a small amount of cash (5 - 10$).
