Employee finds human heads on Southwest Airlines airplane

An Arkansas coroner was investigating after a cargo shipment of 40 to 60 human heads was discovered by a Southwest Airlines employee, NBC DFW reported Thursday.

The container of heads was found in Little Rock, Ark., last Wednesday and was set for transportation to a Medtronic research lab in Fort Worth, Texas.

“It wasn’t labeled or packaged properly,” Ashley Rogers, a Southwest spokeswoman, told NBC DFW. “They called the local authorities.”
