In the final episodes of the ID series, Natalia's continued communication with her prior adoptive family wreaks havoc on the DePaul household as they try to help her understand how she's been exploited.

Anna Newlin, who once lived with the Mans family, defends the Mans family on camera, but then suggests to producers of the show that Natalia was struck with a belt and kicked down a flight of stairs by the Manses. "There's some things that can land [Cynthia] and Antwon in jail for a long time," she says in a voiceover.

Natalia Grace reveals why she finally cut ties with her adoptive parents after fleeing their home to live with another family -- and the moves she's making to take "control over my life."

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.

Who are Natalia Grace's adoptive parents? Here's where she stands with the Barnetts, the Manses and the DePaul family.
