Hello all! I've been reading and keeping up with the thread for a couple days now and all the thoughts and leads everyone has been posting has been inspiring, so I thought maybe I would leave my thoughts here to inspire anyone else!
My main focus has been the motive of this crime. If money was the motive, then it is my belief the ransom notes would have included either Proof of Life or some form of an open communication line, therefore assuring they receive the money they want. I think regardless of intelligence, the kidnapper(s) would have known no money would exchange hands until there is Proof of Life.
So if money isn't the motive, then my next best guess is attention. The fact these ransom notes have been delivered only to news stations would corroborate this. Not to mention, SG's obvious ties to the news. It feels like a lot of this crime has been done to capture the attention of the country and News Cycle. (Another thought along these lines is the fact the response to the kidnappers from SG and LE may have been purposely not posted through news channels in order to deny them that fame, and therefore prompting the kidnapper to reach out again.)
That has been my line of thinking thus far, and if anyone disagrees with the above I would love to hear it. It's hard poking holes in your own theories haha.
On another note, I keep seeing mention of an Uber Driver and I can't seem to find where that comes into play, as far as I know NG was dropped off at home that night by her family. If anyone has a link or can quickly clear that up for me I would appreciate it.
