She was rushed to hospital, but pronounced dead there.
Rock Island County Coroner Brian Gustafson determined the little girl had suffered bruising and a fractured skull from the fall, but that she was still alive; the preliminary cause of death he said was exposure to the cold.
"At this time there's no evidence to indicate it’s nothing other than a terrible, horrific tragedy," Gustafson told KWQC.
"It's being investigated as nothing more than a tragic accident. She was a beautiful little girl."
