A 3-year-old girl died after she was struck by a horse-drawn wagon, according to York County Deputy Coroner Steve Cosey.
The horses had panicked as they were being unhitched from the wagon, Cosey said.
The girl, whose name had not yet been released, died of head and neck trauma, he said. There will be no autopsy, and the death is ruled as accidental.
Two other girls declined medical transport on the scene, Cosey said.
One by one, Amish buggies rolled up to the farm on Thompson Road in Lower Chanceford Township late Tuesday night.
Donald Peters, who lives a short distance away on Route 74, said a relative of the family asked if he might be able to pick up the grandparents in Lancaster County.
Peters drove off a short time later after an Amish boy came to get him.
State police did not immediately release any additional information.
