ZR doesn’t assert or eliminate any scenario. In fact that is noticeably absent. He said they have nothing.
Towards the end he mentions the length of the investigation and sort of trails off as he says that gives him hope there will be information if someone did it to her. He didn’t sound too confident about that aspect.
She had already purchased gifts/items that she was bringing and showed them in an earlier communication.
He says she drove off her expected route. [but how would he know unless a camera caught her driving or LE told him]
He says she did not like to drive but would follow GPS instructions for a short cut.
He never indicates that there is a vehicle, person, or a location of interest.
He doesn’t know where she was from when she was last seen to the car discovery.
