All the discussion about where LTGs and 2MWs, 1Bs, location and timing has come from assumptions that they were all on the gravel rd near the gate at the start, moving away from his car. But everything could have happened as everyone was moving in the direction towards his car.
He arrives on scene 20 minutes prior to 1st call and begins foot patrol. He could have walked all the way to the building and be on his way back to his patrol car. Or he could have taken a route off the road towards Precision Chrome and the treatment plant (clockwise or counter clockwise). Not very thick terrain, easily walkable.
3 men could be coming from anywhere. Gravel rd from Rollins, woods just east of the gate...Lots of directions and still not see his patrol car. They could easily enter the road or be on the road with their backs to the LT, as he re-enters the road, or sees them enter the road.
I believe now, with Walkers recent info, that none of his calls came from LTG while he was in his car. The calls that begin with a Screetch seem to all come from a radio on a vest. Calls from the cars don't have that. Someone correct me if I'm wrong.
Put all that into the scenario, and it fits the timeline. Including the 20 earlier arrival time.
Side note to consider. We all also assumed the first shot hit the vest. What if that was the second shot, with the sole purpose to destroy the cell phone. I know calls can be tracked. Along with time and duration of those calls. And so can texts. But the contents of those texts cannot be retrieved by the phone provider. The content is stored on the device itself. Again, correct me if I'm wrong.
Also, it was brought up about 911 calls from cell phones being tracked. I have had the police at my door saying a call came from my house. He was quite certain of the accuracy. I just said sorry, not from here, and he left. Talking to my neighbor later and the police also went to his house. It turns out his kid meant to call 411 and called 911 by mistake, freaked out and hung up. Our houses are only 20 apart.
