What? Am I a cell phone expert? Did I claim to be? I was giving the things that trip ME up for the boat theory. My theory is a theory, just like yours and the other 5000 people following this thread. It's all opinion. Only in the end will we know which one happened to be right. And I will be glad to know, and couldn't care less if mine was right. Mine is only used as a tool to sleuth until I no longer have to because the answers are known.
On this video right here at 5:40, they show a phone track from the house to the bridge. That is what I was talking about. Is there something that shows a track of a boat that has been published? Ok, then. Then I guess we are still looking and thinking and speculating, but I have a little something concrete that is what keeps me away from the boat theory at the moment.
Watch where you land. Some of us use both logic and facts, as well as a respect for other people's opinions, when we post.

To each, his own.
Edit. Also, in brainscratch with klein, right after the 30 minute mark, he says he had gps signal analyzed. If they have gps, they know the track.
Edit #2- I try not to listen the the sherriffs info cause I don't trust his word.
