The third season of the ID channel docuseries brings to light allegations of financial and physical abuse against Natalia’s new adoptive parents, Antwon and Cynthia Mans; THR reached out to the Indiana Police Department about the allegations.

Natalia Grace Mans (née Barnett) was adopted by Cynthia Mans and Antwon Mans after she escaped alleged abuse from her former adoptive parents, Michael Barnett and Kristine Barnett. However, the Mans family may not have been the heroes that the Ukraine native needed.
