PHILADELPHIA (AP) — Four social workers were among nine people charged Thursday in the death of a disabled 14-year-old girl who authorities say wasted away from neglect before dying at 42 pounds.

Danieal Kelly's mother was charged with murder; counts against other defendants range from involuntary manslaughter to perjury. District Attorney Lynne Abraham said any of the nine could have foreseen the horrific fate of Danieal, whose emaciated body was found in her mother's squalid house covered with bone-deep, maggot-infested bedsores in August 2006.

Abraham had scathing words for the city's Department of Human Services, calling its handling of the case "callous, indifferent, unconscionable" — and all too familiar.

"Danieal did not fall through the cracks," she said. "It was a failure of institutional inclination. Saving Danieal was just too much trouble."

Warrants were issued for all nine defendants Thursday. Andrea Kelly, the mother of Danieal (pronounced "Danielle"), was charged with murder, and father Daniel Kelly, who did not live with the family, was charged with child endangerment.
