She is an orphan living in Rapture whom private investigator Booker DeWitt became attached to and later took in after the orphanages were shut down by the city council. Like many children in Rapture born in lower-class families, Sally was orphaned by her parents and sent to a Little Sister's Orphanage, a business front for Frank Fontaine and Fontaine Futuristics. Because of exposure in a smuggling ring, Fontaine was "killed" resisting arrest by Ryan Security.
