In Daddy's flashback, it's revealed that she ran an independent escort service that catered to wealthy, older businessmen. Although she genuinely seems to care for the women who work for her, the story takes a dark turn when one of the girls is found dead after spending the night with an important client. Instead of calling 911, Daddy instructs the man on how to get rid of the body and come up with an alibi. We don't know for sure that this specific death landed her in prison, but it seems like a strong possibility.
