Police responded to their Lakeline Boulevard apartment in May after receiving a report from the Texas Department of Family and Protective Services. When they arrived, police said the girls, five and six, were found with their mother in "deplorable conditions" and that they were unable to communicate other than with each other in their own language made up of various sounds.

The children are now in the custody of Child Protective Services.
