Billy Bob Thornton’s estranged daughter Amanda Brumfield was sentenced to 20 years in prison Thursday after she was found guilty of aggravated manslaughter of a child in May.
Brumfield, 32, was found guilty in connection with the 2008 death of her best friend’s daughter, 1-year-old Olivia Madison Garcia, who she claimed hit her head after falling while trying to climb out of a playpen.
A source close to Brumfield told RadarOnline.com that her defense team plans to file an appeal of the sentence.
She had been found not guilty on first degree murder and aggravated child abuse charges in Olivia’s death.
In a strange coincidence, Amanda Brumfield’s trial took place in the same courthouse where Casey Anthony’s trial was held. Anthony was acquitted of killing her daughter Caylee Marie Anthony.
