I was just trying to find that very statement. I couldn't remember if she actually said his switch, or "one of his electronic devices" (which could be a number of things). Do you remember exactly when the statement was made? Was it in the secretly recorded conversation, her written statement, or a social media (unapproved source) post?
I am curious because #1) most newer vehicles have the capability to become a hotspot (especially if a subscription to Sirius/iHeart, On-Star, etc. is purchased), #2) some devices will connect to a vehicle's Bluetooth (for example; my Kindle and iPhone will). If so, this would enable LE to track exactly where the device was at any given moment. Does a switch have Bluetooth capabilities? Anyone know? TIA
