Billy Bob Thornton's daughter has been sentenced to 20 years in prison.
Amanda Brumfield - the 32-year-old offspring of the actor and his first wife Melissa Parish - was found guilty of aggravated manslaughter earlier this year and today was sentenced for the offence.
In May, a court convicted Brumfield over the 2008 death of her best friend's 12-month-old daughter Olivia Madison Garcia, who she had claimed hit her head in a fall as she climbed out of her playpen.
However, prosecutors had argued it was "impossible" for the three-and-a-half inch skull fracture Grace suffered could have came from a fall at that height, though her defence claimed it could have aggravated an old injury.
A source close to Brumfield - who had been found not guilty of first degree murder and aggravated child abuse charges - told RadarOnline.com that she plans to appeal the sentence.
