Authorities in Washington are asking the public for help after a thrift store in Washington received a highly unusual donation.

Someone dropped off a box with three skulls at the Goodwill in Bellevue last month. Two were adults and appeared to be the kind used for medical or educational purposes, the King County Medical Examiners Office said.

But the third was of an Indian child, according to the medical examiner. The skull was formed in a way that suggested it had been placed in a cradleboard as an infant.

Authorities are hoping the person who dropped off the box will come forward with information about the child. If it can be identified or affiliated with a tribe, the skull will be repatriated for reburial.
