Natalia Grace was welcomed into Michael and Kristine Barnett's family 13 years ago when they adopted the six-year-old orphan from Ukraine.
The adoptive parents were initially overjoyed at welcoming the youngster into their family home in Indiana, but their world was soon shaken upside down.
Michael and Kristine started to doubt Natalia's age and claimed the youngster was actually an adult at the time of the adoption, even going as far as getting her age legally changed by 14 years.
