A shipment of 18 severed heads has been intercepted at Chicago's O'Hare Airport.
The severed body parts still had skin on them and were wrapped in plastic, Cook County Medical Examiner's confirmed.
Sources at FOX 32 News say they came from Italy, and may have been sent to be used for some kind of scientific research or a medical experiment.

The Chicago Sun-Times reports no foul play is suspected in the find. It quotes Brian Bell, a Chicago-based spokesman for the Department of Homeland Security as saying: "There’s no issue with the transportation of body parts for medical purposes
The paper added: "Sources said the specimens are human heads, still covered in skin."
As macabre as it sounds, The Atlantic points out 12 human heads were found back in 1986 in a UPS package.
"A doctor in Philadelphia said he shipped the heads to a medical training facility in Colorado," reported the AP at the time.
