Cruel Diana Franklin tied her adopted girl to a tree by her neck during a shocking six-year campaign of torture.
Franklin, 48, also beat the naked child with a belt buckle and held her at gunpoint, according to reports.
The American Civil War re-enactor - who served in the US Air Force - wrote in a diary how the girl was her "slave".
She repeatedly deprived her daughter of food, water or clothing.
Sentencing her, Judge Bobby Peters said:"To me, you are just an evil woman."
