The estranged daughter of actor Billy Bob Thornton has been found guilty of aggravated manslaughter of a child in Orlando.
Prosecutors say 32-year-old Amanda Brumfield was convicted Friday. She is expected to be sentenced in July.
She was acquitted of first-degree murder and aggravated child-abuse charges.
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.
Brumfield's father, Billy Bob Thornton, is best known for the movie "Slingblade" and his marriage to Angelina Jolie.
