The estranged daughter of actor Billy Bob Thornton has been sentenced to 20 years in prison for the 2008 death of a child in her care.
Amanda Brumfield, 32, was convicted of manslaughter earlier this year.
Authorities say Brumfield killed her best friend's daughter during an overnight stay in October 2008.
Brumfield says 1-year-old Olivia Madison Garcia was trying to climb out of a playpen and hit her head. The defense suggested the fall may have aggravated a previous injury, causing her death.
Prosecutors say it's impossible that a fall from that height caused a three-and-a-half inch (9-centimeter) fracture on the back of the girl's skull and the bleeding and swelling found in her brain.
