4 human skulls bound for U.S. found in box at Mexican airport

Authorities in central Mexico said Friday they found a strange holiday-season package at a local airport: four human skulls being shipped to the United States.

Mexico's National Guard said its officers were called to an airport in the city of Queretaro after an X-ray detected strange shapes in a cardboard box.

The box was being sent from the southern city of Apaztingan, in Michoacan state, to an address in Manning, South Carolina.
