Adoptive family's nightmare: When the 'child' turns out to be an adult sociopath.

A family in Indiana who adopted a young girl from Ukraine but later alleged she was an "adult masquerading as a child with intent to harm their family" are speaking out about the ordeal 13 years later. The parents petitioned a court to legally change Natalia's birth year from 2003 to 1989, which was granted and changed her age from 8 years old to 22. The family then moved to Canada with their biological children, where their oldest son was slated to start college. In 2019, the couple, who have since divorced, were charged with neglect of a dependent. The documentary, a three-part series that will kick off on May 29 on Investigation Discovery across three consecutive nights, will feature "bombshell interviews with members of Natalia's adoptive family," such as Michael Barnett and his son, Jacob Barnett, as well as legal experts, friends and neighbors.
