When I go to my home, or a few trusted others, my phone connects automatically to the Wi-Fi. Is there a record somewhere of devices that connect to a Wi-Fi network, that would be viewable?
I'm just thinking aloud, but if an accident had happened at the dinner, and it was decided that it needed to be covered up, someone could have driven to the NG's house, opened and closed the garage door to make it seem like she was dropped off, then gone back to finish getting things in order. The person then could have put NG in the car, put her purse, phone, watch, etc., in a backpack and driven it all back to her house. Disabled the camera, taken the personal items inside and arranged them as though NG had done it, then driven NG elsewhere, at which time the pacemaker would have disconnected from the phone.
But if there was a record that her phone connected to her home Wi-Fi around the time the garage door opened, it would support that she was probably actually dropped off at that time, and the person who took her is more likely a stranger.
