A judge ruled dismissed the charges against Kristine Barnett for child abandonment and neglect. Michael Barnett filed a similar motion that will likely have the same result due to the ruling made on Kristine's motion. The pair will still face charges of abandonment & neglect of a dependent, due to Natalia's disability.
Even though the court essentially ruled that they cannot make a determination regarding Natalia's age, and upheld the previous decisions, there seems to be mounting evidence that she was a child when she was adopted by the Barnetts. The prosecution claims there was a DNA match for the woman in Ukraine, Anna Gava, who claims to be Natalia's mother and says that she was born in 2003.
We'll have to wait and see what new developments happen with this case.
