A report of a human skull found in a donation box brought police to a Goodwill store in Arizona. 

An employee called in the gruesome find, according to CBS affiliate KPHO-TV, because they feared it might be related to a criminal or missing-persons case. In a photo shared by the Goodyear Police Department, the skull is withered, with what appears to be a prosthetic blue eye attached to the right socket. 

Goodyear Police Department public information officer Lisa Berry said at a news conference that the medical examiner’s office studied the skull and found that it is likely not related to a criminal case. 

“We did speak with the medical examiner’s office, they did confirm that it is fact a human skull, but at this point, and this is preliminary, it appears to be historic, ancient and does not appear to have any forensic value at all, and what that means is that no crime is really attached to this skull,” Berry said. 

A customer told KPHO-TV that they were shocked to hear about the find. 

“I’ve never heard of anything donated like this, especially here. I come to this Goodwill all the time and I’ve never heard of anything that crazy being donated,” said shopper Sydney Steele.
