Last American Slave Ship Possibly Found

In a remote river delta on Alabama's Gulf coast, partially hidden under water and mud, may be the answer to a mystery that has baffled scholars for more than 150 years. If experts' suspicions are correct, it's the long-lost wreck of the Clotilda -- the last known ship to bring human cargo from Africa into the United States. Its precise location has eluded archaeologists and historians since the vessel was burned in 1860 by slavers seeking to hide evidence of their illegal trafficking.
