Two skulls found at O'Hare

Police say U.S. Customs officials screening cargo at Chicago's O'Hare International Airport located two skulls.

Chicago police spokesman John Mirabelli says the bones appear to be human. He says they've been turned over to the Cook County medical examiner for an autopsy.

Mirabelli says customs officials found the skulls Tuesday afternoon in a package along with a dental model. He says they may be used for teaching or medical practices.

Mirabelli says neither the package's destination nor where it came from is clear.
