I have been thinking/theorizing about Jenna's activities that night. If she left the gas station on Cheshire Bridge at 11PM (the only one that we were provided a time for) and drove to the Handi Mart to Person #1 at 11:45, Jenna would have traveled almost immediately to reach the Handi Mart on Joseph Boone Blvd. The Joseph Boone Blvd.(granted it could be the other Handi-Mart on the West side) location is right next to the Vine City area---near the Bluff's, which is one of Atlanta's most dangerous neighborhoods. This area suffers from tremendous blight, with vacant and boarded up houses on each every street and is known for high crime.
With this thought in mind, IMO it is possible that Jenna never left this area that night. This scenario left me with questions about her parent's home and the missing tapestry. The sad realization that I came to is with an individual's phone and keys it would be possible to obtain directions and access to a home that you have never been to. So, here is one of my full theories (all MOO):
Jenna drives her Mom's car to the Cheshire gas station after making plans to meet Person #1. She then drives to meet Person #1 at the Handi-Mart. In the space of several hours, something happens to Jenna. I think that the person/persons responsible send the text to the SC friend and use prior knowledge or her phone to return to the parent's home. At this point, they collect the suitcase and take the tapestry as a red herring. They wipe down the Mom's car. They take the items collected from the home and place them in Jenna's car and leave with her car. I don't believe that this person(s) would have had any knowledge about the insurance. They then lock the door behind them. IMO, they take Jenna's car and store it somewhere (maybe a garage, behind a building) for several days. When Subie calls the phone that morning and it rings, I question whether the person still had the phones in their possession. I wonder if Subie's call could have caused them to power off the phone. (If this would be the case, the ping information could be why LE is so quiet.) As more and more flyers go out and news coverage starts, the responsible party(ies) moves the car to Defoor Place, places Jenna's day bag in the car and wipes the car down. They leave with Jenna's lanyard.
With Jenna's lanyard and phone, they would also likely have her address for the apartment as well. (How many of us have "home" or "frequent locations" stored in our Map apps?) They could have waited until no one was home and removed items from there as well.
Please feel free to chip away at the above. The only thing that I can think of that puts the above theory to bed is the sighting of Jenna driving someone to her parent's home, but to my knowledge that was never confirmed. I don't believe she left of her own accord but, I cannot figure out the tapestry!
