Police asked for the public's help to locate whoever donated a human skull to an Austin, Texas, thrift store.
Homicide Detective Derek Israel said Wednesday that foul play was not suspected in the person's death. He said he just wants to know how the skull came to be in an unspecified container left at the store.
Goodwill staff discovered the skull while sifting through donations July 16. A spokeswoman said it could have been gifted up to a week prior to its discovery.
Israel said the skull is from an adult. No other details about it have been released.
This is at least the fourth skull to be donated to the international nonprofit this summer. Three were donated in July to a Goodwill store in Bellevue, Wash.
