Let me ask everyone a question, if the intimate relationship between KB and PF is what it seems to be, if they were not really in one, is anyone able to consider that another person might be responsible for her disappearance? PF gets the child and goes on his way. KB had recently met someone and the two make plans for that evening. Maybe they agreed to have rolls at her place. When this person arrives, he says, let's go out and do something instead. Now the rolls are sitting on the counter, she ran out the door in a rush not expecting to go out that night. I would have to say, in the times we live in, it's possible for someone to meet someone online and not really know about them. I'm going to say this person was not someone KB knew that well but, he seemed nice enough. Is it possible she got involved with a crazy online dating person The plan for this person was always to do something harmful to whoever gave them the first opportunity. Maybe he wasn't from the area. I could imagine a scenario where KB had not been harmed but she was definitely taken against her will. This person decided to take her back to wherever he was from, which had them pass certain Idaho towns. She was forced to send the work text and then she managed to get her phone and turn it on just long enough for it ping off a tower somewhere. After that, who knows.
LE was given some info or they pieced something like this together and they are back at the condo trying to identify whoever it is. This at least explain why it seems they don't have video of anyone driving a certain vehicle near her home or in town. They wouldn't know what kind to look for. I think this is something that is pretty possible.
