A 3,200-year-old mummy mask at the center of an international dispute will remain in St. Louis following a ruling by a federal judge.

The U.S. government sought to return the funeral mask of Lady Ka-nefer-nefer to Egypt, claiming it had been stolen before the St. Louis Art Museum purchased it from a New York art dealer in 1998. But U.S. District Judge Henry Autry in St. Louis ruled on March 31 that the mask can remain with the art museum.

The U.S. Attorney's office is demanding that the Saint Louis Art Museum give up an Egyptian mask because it's stolen property.
