It is entirely possible.
The key thing we know for sure about this case is that while Mary’s Comet was being parked by someone at Lenox Square on Friday morning, someone else, described by a witness as an unshaven middle-aged male, had pulled into a gas station a few hours earlier with a woman, described as bruised and bloody, in Charlotte, NC, some 260 miles from Atlanta. It is irrefutable that this woman authorized the use of Mary Shotwell Little’s gasoline credit card. A similarity described bruised and bloody woman, accompanied by a similarly described unshaven middle aged man, or two unshaven middle-aged men by some accounts, would irrefutably authorize the use of that same card several hours later in Raleigh, NC, some four hundred and twenty miles away from Atlanta.
There had to be least two, or three, abductors involved in Mary’s kidnapping, thus a criminal conspiracy.
For me, this reality takes away any theory based on a single perpetrator.
After some more consideration I have to agree with you this most likely had something to do with Mary's job at the bank.i dont't think it was any coincidence that her husband was in training to be a bank examiner, the very person whose job it is to report misconduct at a bank. Could someone have not wanted him to complete that training?
I think it is unlikely that Mary was abducted from the mall but probably met someone that night. I feel like she was gonna use the groceries as an excuse to not stay long. Now these are just some thoughts but neatly folded clothes makes me think of doing laundry (money laundering) and a half cut stocking makes me think of a bank robber with it over his head. The stolen tag and purchase in Charlotte could have been a warning to the Shotwell family just in case Mary had said anything to them about something. The tag was probably only used during the purchases and then switched back to the rightful one. The receipts were signed in the husbands name and I wonder if Mary always did this. Maybe she did but if not could this be a warning shot at him?
I believe Mary was murdered shortly after signing the receipt in Raleigh. The perps mission was complete and I think they headed straight back to the Atlanta area. No need to chance bringing Mary back, I believe she was disposed of somewhere just south of Raleigh probably not far off the southbound lane of 85. If her disposal was as well planned as the rest the site was most likely prepared and waiting.
I also have some questions about Marys car being returned to the mall and the way her boss acted that morning and then there's the fact that whoever returned the car took the keys. Now taking the keys could just possibly have been habit or to make sure the car wasn't moved or stolen before it was discovered but for some reason I get the feeling there may have been something else on a key chain that someone really wanted.
And I do think the Diane Shields case is connected. She told at least one person that she was working as an informant and I tend to believe it but it doesn't neccesarily matter if it was true because if she was telling this to people then that could be enough to get her killed. Her car was found in the parking lot of a dry cleaners (more laundry) and then there's the cookbook in the trunk. Cooking the books anyone? There is a picture back on this thread of the car and it was placed directly beneath a no parking sign. Could that also have a meaning? I don't know but that's enough thoughts and feelings for now.
