I'm not sure there are any truly productive conversations to have about this case, at this point, not without more information. JMO
It is by no means a "hot case."
My opinions only, no facts here:
An overriding difficulty with resolving the Holly Bobo case is explaining the strategy of the unidentified suspect or suspects.
If you research other solved or partially-solved (e.g. Morgan Harrington) female abduction cases that involved a vehicle, you will see that the purse (=lunchbag) and cell phone are discarded at the crime scene or as soon as possible after the abduction (say 1 to 2 miles away), or are never found. If the abductor was careless or stupid and the victims cell phone stayed with them and had power, then
the suspect identification and arrest came quicker (I am aware of the contra-indications of the Michelle Parker case, but this case is also somewhat atypical with regards to recovered evidence). I have seen a separation of a mile between the cell phone and the purse of the victim in some cases (this suggests that the purse was examined for money or trophies or that the crime is not what it seems to be), but overall I expect all personal belongings to be found closer together. As an example, I cite the Morgan Harrington case. In spite of all the after-the-fact sightings of her on some strange walkabout down the roadway, her purse and cell phone were found together in the parking lot outside the music concert and presumably this is exactly where she was grabbed. Her personal belongings were dumped on the spot.
Holly Bobo was not abducted for her money or jewelry. The timing of the lunch bag find suggests that this could have been discarded not long after Hollys disappearance. Hollys cell phone is more problematic. It was found so much later, that unless it was very well hidden in the weeds, it could have been placed there days later. Using my logic cited above, Hollys phone would have been deactivated not very long after her disappearance, but not necessarily dumped immediately. Whether Hollys purse or pocketbook with her ID/credit cards was recovered is of great importance. Maybe the investigators could hold a press conference and tell us only what THEY DID NOT FIND and WHAT THEY DO NOT KNOW. I mean, would this simple request truly endanger the investigation?
When females disappear of their own choice, they commonly leave ALL of their personal items at a provocative location, such as their house, in their car, in front of a cafe, etc. Or, they take all of their belongings with them.
And then there are theories that Hollys abductor was someone from out of town who was vending for a local event or just some opportunistic stranger passing through: this does not fit because the responsible person KNEW Hollys schedule down to the scale of minutes, AND was intimate with the relative safety of the situation. Seriously, if you were from out of town, would you follow Holly home onto a rural property in Tennessee, wait all night next to her house, and in the morning spend 5 to 10 minutes at the kidnap site discussing politics and weather with your victim? (check my previously-posted timeline on Websleuths for the possibility of this 5 to 10 minute safety period for the perpetrator)
I am now studying the Bible Hill area, because it is approximately mid-way between the abduction site and the lunch bag find. The precise location of the lunch bag could be meaningful and significant, totally serendipitous, OR it could have been deliberately planted in that specific location in a crude attempt to deflect suspicion towards someone else that lives nearby.
In summary, the official details of the case and the placement of the evidence has a personal, local, insular, and naive feel to it. It seems to me that the perpetrator was someone from the immediate area who knew Holly through previous and/or present associations AND knew her daily schedule. I also have a hunch that this person has since talked or hinted about the crime, and now it is up to those he communicated with, whether or not they want to take the legal risk of going down with him or coming clean. In my judgment, the case remains solvable.
