8-year-old Kamyah John became separated from her class during a trip to Dorney Park.
The little girl says she left the bathroom and her group was gone.
Kamyah used a stranger's phone to call her parents in Brooklyn.
Her father was furious when the bus returned without his daughter late last night.
"They got to tell me, who is responsible for this. This is pure negligence," said Kamyah's dad.
A trip chaperone told Action News, "I believe they did everything humanly possible to ensure that she was sought after.
Kamyah has relatives who live near Dorney Park and she will stay with them until someone can drive her back to Brooklyn.
