Her mother, Ann, said her family had fallen on hard times and that they took out a loan that eventually spiraled to about $6,000 in debt. With money-lenders threatening her, Ann took up an offer from a woman who approached her promising big money for her daughter's virginity.

Sephak said her mother was paid $800. But after Sephak's return, her mother began pressuring her to work in a brothel.
