That is good sleuthing. Thanks.
The theory of one of KK's burner phone maybe got assigned the same phone number that used to be assigned to a person named SR seems plausible because on Page 20 of the arrest warrant, it says:
""Open Source database checks of that number reveal it to be ASSOCIATED with....."
So that is how they got SR name, address, and map is by open source database checking similar to what you found too. It doesnt say in the arrest warrant that they were placing the pinging of the phone at that address. Just that they looked up the address tied to SR.
We all know a phone number usually is assigned to just one person so maybe that is what happened in that KK may have been assigned SR's old number on KK's new burner phone. This would explain how when KK saw PF calling KB's phone (which she had most likely), that she turned around and called PF on her burner phone.
To clarify a previous comment. I still dont believe in the other coincidence about the other text and wizard of oz reference. LOL
But this one maybe explainable that KK may have had a burner phone and maybe SR was innocently dragged into the arrest warrant due to her number still being associated to the burner phone number.
Now my head is spinning like the rest of us.
