NORFOLK, Neb. (AP) — A Norfolk woman whose 4-year-old daughter has died has been charged with intentional child abuse resulting in death.

Jail records say 21-year-old Carla Montoya remained in Madison County custody Monday. Her attorney didn’t immediately return a call from The Associated Press. Montoya originally was charged with negligent child abuse.

Madison County Attorney Joseph Smith says Montoya’s daughter, Caylee Hoehne, was pronounced dead Sunday evening at an Omaha hospital. She’d been flown there after being treated at a Norfolk hospital for a skull fracture and other injuries.

Court documents say Montoya told Norfolk investigators that she had tossed Caylee into her bed three times between 11 a.m. and noon on March 12. Montoya said she thought her daughter may have hit her head on the bed frame or a wall.
