TALLAHASSEE, Fla. (AP) - A daycare worker from north Florida is being held in jail on a manslaughter charge for the death of a 5-month-old.

The Leon County Sheriff's Office said 55-year-old Barbara Knight was arrested Monday and charged with the child's death. A sheriff's office report says she was taking care of the child on Sept. 17 at the Kids Club Preschool. The child was cold and unresponsive when deputies arrived. He was pronounced dead at the scene.

An autopsy report says the child died from blunt force trauma. The Tallahassee Democrat reports that an investigation by state welfare officials and other agencies showed that the child was under the sole care of Knight at the time of his death.
