The Tennessee Attorney General is investigating the mysterious investment company that attempted to have Graceland, the late Elvis Presley's mansion that is one of America's most successful tourist attractions, sold at a foreclosure sale.

The company, Naussany Investments and Private Lending, claimed that the late Lisa Marie Presley used Graceland for collateral on a loan, but actress Riley Keough, Elvis' granddaughter, filed a countersuit claiming that the documents and notarization were falsified. The claim has since been denied. (Technically, Elvis did leave the building; he's buried on the grounds with his parents and daughter, among others.)
