OCOEE, Fla. -

Amanda Brumfield, the estranged daughter of actor Billy Bob Thornton, was sentenced Thursday to 20 years in prison for aggravated manslaughter in the 2008 death of a child in her care.

Brumfield was convicted earlier this year in the death of her best friend's 1-year-old daughter in October 2008.

Orange County Medical Examiner Dr. Jane Garavaglia testified that the death of Olivia Garcia was intentional.

Police said Brumfield waited more than two hours to call for help after she said Olivia fell out of a playpen.

Brumfield told investigators that she was babysitting Olivia in her Ocoee home when the child lost her balance and fell about 2 feet. She said Olivia was fine, and she even fed her a banana, which is why she waited two hours to call for help.
