I don’t find it especially revealing that they are looking for accomplices. That would seem a “must do” part of any investigation of this type.
As for the aviation fuel, it makes me wonder if they have more than just a “possibly theory” regarding that point.
Some of this seems like speculation.
The aviation fuel angle is more than just speculation. From the other thread that focuses on it, investigators found bullet embedded in the walls of the fuel tank.
Then if you look at the graphic in reply 2, it indicates the broken window to our left and the shooter’s right was used specifically in targeting the tanks. Which makes sense because it faced directly east, towards the tanks. That window faced at an angle away from the festival grounds, so it was basically only useful for targeting the tanks.
Now the following is my speculation since I didn’t read the LV Review Journal article about the fuel tanks, so here goes. The shooter’s opening round of shots were aimed exclusively at the tanks. If you watch any of the home-made vids from within the festival grounds, you can clearly hear the shots, but no one moved or fell. So it seems the bullets were flying at the tanks instead.
After a few seconds delay (presumably when the shooter moved from the gun aimed at the tanks to the gun at the other window), the 2nd set of shots began, and that’s when the festival goers began to get hit.
