Schmerty, here's what it means to me.
In the beginning of the investigation, investigators had to do a 360-degree look at every possibility. As the investigation went on, it became evident that they could exclude many possibilities, which narrowed their focus. As the Sheriff said, some things that they suspected early on, they no longer suspect.
The focus of the investigation has narrowed to the single possibility, the single suspect, and I believe that they have a lot of evidence against that person. That person most likely tried to cover her tracks very well, so it's taking time to unravel the case, to deconstruct exactly what happened.
They aren't as much in the evidence gathering phase anymore, as far as gathering huge volumes of disparate tips and such, and are focused on the most plausible explanation for Kyron's disappearance.
So now they don't need the huge body of investigators that they had before, because they are more focused and the picture of what happened to Kyron has become clearer.
It's like writing a thesis. In the beginning, you gather reams of info, research it all, make notes, and exclude the things that have nothing to do with the topic. Then you move into the writing phase, where you begin to compile the research into a thesis that explains the topic. It takes laser-like focus to write a thesis. Research, not so much.
I believe that investigators are in the process of "constructing the thesis" now. And it doesn't take 25 investigators to do this. I'm sure if some new details come in, then they will look into them. But I believe that investigators have a good body of evidence and a clear idea of what happened to Kyron... they're in the process now of constructing an unimpeachable case.
My opinion.
