Re first bold by me: I'm curious 1. why you think she is no longer in the vehicle after that intersection, and 2. where do you think she is at that point?
Re second bold by me: And do what, search that area again?
My opinions only, no facts here:
Before I respond to you, my friend, there were two other inquiries I would like to comment upon.
As for the timeline, we basically know that Holly was reported abducted at 7:30ish AM. The police were said to have responded very quickly, within minutes. Beyond that, read the news reports timeline from various sources that was provided by norest4thewicked. It is a list of contradictions and demonstrates why I am currently following my own theories in this case- I have very few facts, if any. Did the neighbor hear a scream and if so, did they call 911 or not? Did the neighbor hear a scream and not call 911? After all, a scream can be a generic sound, easily confused for other causes than an abduction. When exactly did the crime occur? None of these seem firmly answered by the news reports. But let us say that there really was a neighbor who heard a scream. However the cops might determine they live too far away to have heard anything relevant to the case, or that the reported time of the scream does not correspond with their timeline. Until law enforcement holds a press conference and states that this scream occurred at such-and-such time and is relevant to the case, we cannot be certain. If I were given the choice of saying what I think the police know or attending a seminar on cockroach anatomy, I would guess:
The reported time of the crime was closer to 7:30 AM or even a little before. The brother called 911 first, and then called his mother. The mother or her designate then also called 911. The neighbor did not call 911, but informed police about the scream when they were going door-to-door shortly after the incident. But the contradictory news reports allow for another sequence of events after the crime occurred: The brother called his mother to tell her what happened, and she said to call 911. The brother then called 911. Then the mother, worrying about it, also called 911. More of the cockroach anatomy seminar? The conflicting reports also allow for another scenario: The neighbor heard a scream and called Holly's mother. About the same time, the brother independently called 911. Then Holly's mother called 911. Then the mother called her son to see what was going on. See how confusing this becomes? This is what happens to sleuthers when they have mere crumbs of information to work with.
OK, good buddy. The following theories are based upon the assumption that the mere scraps of information we have received are moderately accurate. If the information we have received is wildly inaccurate, I will still stick with the route I describe for reasons that cannot be stated on websleuths. Holly was led from the carport towards Swan Johnson Road and placed in a vehicle, possibly a van or the trunk of a car. My third choice would be a vehicle with tinted windows. From Holly's house you can go south into a more populated area where you may be seen, or north into a less-populated area where you may not be seen. When you go north, you shortly come to the intersection of 5 Forks and Swan Johnson Roads. Now you can go left, right, or straight ahead. Left or right turns put you in areas with less chance of being spotted. But the evidence found north of Bible Hill suggests that a right turn was made. But between this right turn and the evidence location there is a fair amount of development and many good chances of being spotted. I assume that a perpetrator would not be merrily throwing evidence out the window of a vehicle or stopping to toss it, if the victim was still with them. It just does not make sense. So, I think about looking further SE of the previous search area at the junction of 5 Forks and Swan Johnson Roads. It is a longshot of course. But the reported locations of the two pieces of evidence in this case suggest to me an inexperienced perpetrator who is trying to FOOL THE POLICE. For crying out loud!- experienced criminals leave the evidence with the victim or dispose of evidence in a manner that makes it very difficult to find. Something seems very incongruent about this case.
