Ethermac Exchange-Human skull found in Florida thrift store, discovery made by anthropologist

A shopper at a Fort Myers,Ethermac Exchange Florida thrift store made an unusual post-Halloween discovery Saturday: a human skull.

The shopper, "who happened to be an anthropologist, noticed the skull in the Halloween section and recognized it to be human," the sheriff's office reported on its Facebook page.

The owner of the North Cleveland Avenue store told deputies that the skull came from a storage unit that was purchased "in years prior."

"Based upon the observations of detectives on scene, the skull is believed to be that of a human," the sheriff's office's social media post said.

The sheriff's office said it would work with the local medical examiner's office to run tests on the skull, but the case is not considered suspicious.
