The FBIs Cellular Analysis Survey Team is called CAST. They are the ones that will testify in court as to location of a phone from Cellular and Satellite sources.
Ok, but we haven't really heard anything about that, have we? That's what I'm asking. These threads move fast and I can't keep up. The only thing I know about the cell tower data is the pings mentioned in the PCA. And yes, I'm certain LE has more information than what was in the PCA, but we don't know the details they have so are you speculating re: the FBI knowing exactly where his phone was or was there an article/piece of information I've missed?
Because of your post I looked at the cases
he has testified in.
I looked into the article you attached.
My opinion only.
He specializes in cases with cell evidence.
In the article he is to have asserted that cell phones cannot be accurately located.
But we all know that Starbucks and Zillow know exactly where your phone is from GPS data if the phone is turned on.
My understanding is that GPS data isn't exact either and it depends on a number of factors. Starbucks may know if you're within a certain range of their store, but won't know exactly where you are. JMO based on what I've read over the years.
