“Melanie Billings appears to have covered her tracks with a will. But attorneys say it's not valid.   The last will and testament of Melanie Billings was placed on file this week, at the Escambia County Probate Office. Attorneys for the family said Byrd didn't even leave behind a will. . . . But the family's attorney, Kramer Litvak, says the court doesn't have the power to honor Melanie's requests.”
