The latest purported ransom notes sent to TMZ claiming to know who kidnapped Nancy Guthrie reveal a sick plot to continue to “torment” the missing grandmother’s devastated family for a quick profit, according to a former FBI agent. The notes, which also claimed to know where her body could be found, were sent just as Guthrie’s daughter Savannah Guthrie made her emotional return to NBC’s “Today” show for the first time since her mom vanished more than two months ago.
