The couple allegedly forced both girls — who were about 10 and 15 years old when they were smuggled into the U.S. — to provide labor and services for their own private gain, prosecutors said. The older girl, now 17, wasn’t allowed to enroll in school and was forced to work and give her earnings to the couple, officials said. The younger girl started school in Aurora only after child-welfare workers visited the home. Both girls cleaned the couple’s home and took care of their baby, according to a federal criminal complaint. The girls allegedly weren’t allowed to leave, and the younger girl was allegedly abused.
