3 human skulls donated to Seattle-area thrift store

SEATTLE -- Officials in Washington state are searching for the person who donated three human skulls to a thrift store in a Seattle suburb.

The King County medical examiner said in a statement on Wednesday that two of the skulls were from adults and appeared to have been used in a medical clinic or for instruction.

The third is very old and appears to have belonged to a Native American child. Forensic anthropologist Kathy Taylor said the skull is that of a 5 or 6-year-old and is at least 100 years old, CBS affiliate KIRO reported.

State law requires the Native American skull be returned to its tribe. The medical examiner is asking whoever donated the skulls to provide some details, without penalty, so that can happen.

The skulls were donated last month to the Goodwill store in Bellevue. Workers there realized they were human remains and contacted the medical examiner's office and law enforcement.
