Cargo of human heads

Arkansas airport workers discovered a shipment of 40 to 60 human heads at a cargo facility, after noticing that the package was "not labelled properly".

Employees at Southwest Airlines discovered the clumsily duct-taped containers of heads last week in Little Rock.

After they reported their grim discovery to police, the heads were turned over to the local coroner.

Pulaski County Coroner Garland Camper said: "They were basically in plastic containers with lids that are not air sealed. They were duct taped with minimal information to disclose what was inside."

Further investigation revealed that the heads were being shipped to Medtronic in Fort Worth, Texas, where they would be used by neurosurgeons to study ear, nose and throat procedures.
