The medical centre parramatta seeks information on who donated a set of three skulls to a Bellevue Goodwill store last month.

One of the three skulls, which appears to be “very old” and fragile remains of a Native American child, must be returned to the tribe of origin according to state law, the office says.

The other two appear to have been adult skulls used in a medical clinic or for instruction purposes.

The skulls were dropped off in June to the Bellevue Goodwill at 14515 NE 20th St. Employees at the thrift store realized the skulls were genuine human remains and contacted the Medical Examiner’s Office and police.

Now the Medical Examiner’s Office wants to know who donated the skulls and how they came into that person’s possession, particularly the child skull. The office seeks more details in an effort to identify the child’s tribe of origin. There will be no penalty for anyone who comes forward with information, the office says.

The Medical Examiner’s Office advises that anyone who is given or inherits clinical or archaeological remains can turn them in to the medical examiner.

The office advises anyone with information about the donated skulls – or has other skeletal remains to dispose of – to call the Medical Examiner’s Office at 206-731-3232, ext. 1.
