Jean Jacques Baptiste DuSable and his empty grave

I happened upon an archeological dig the African Scientific Research Institute was conducting in St. Charles, Missouri, in the mid-2000's. They were searching for the grave of Jean Baptiste DuSable, the Haitian founder of both Chicago, Illinois, and St. Charles, Missouri, the first state Capitol, founded in the late 18th century, based on the fur trade.

As television cameras whirred, the archeologists announced that DuSable's supposed grave was empty! All were astonished. The surmise is that the black explorer's grave is under a Catholic church's paved parking lot there is St. Charles.
