I personally think that the fact LE wont release any information or even say a word, speaks volumes actually.
Those of us who read WMBF news here know that they report and update stories frequently. Not always reliable, but it is information.
What other reason, besides securing / recreating a crime scene, and a fatal wreck, does LE completely shut down a road?
And not only shut the road down, shut it down for several hours and not tell anyone a word about why.
Someone may be singing like a canary.
Trial is right around the corner.
They realized that they could spend the rest of their life in prison.
Maybe they started to cooperate, in hopes of being free again one day in the future.
The timeline fits.
The circumstances fit.
The lack of information about the road closure fits.
The location of the road closure fits.
If the shoe fits, wear it.
And from an outsiders point of view, this shoe looks like it fits.
