It's a very odd case as every scenario has some holes. If she was kidnapped for ransom it appears all the ransom notes were fakes. I would think there would have been a physical one left at the house. If it was then just someone who hates Savannah Guthrie why kidnap her and not just kill her and leave her there. And if it was a burglary gone bad you would never take the person again, you'd just kill and leave them there.
