I think she returned to the bar to get her phone and encountered a couple of creeps that were lurking out in the parking lot doing drugs or tweaking or boozing it up. The VFW is pretty much on a dead end street, so they could sit there in the dark and do whatever it was they were doing without having to worry about the cops showing up. She pulls up, by herself, probably bangs on the door and gets no response. They notice this lone woman, and being the opportunists that they are, they approach her and probably strike up a conversation.
If there are two of them involved, one could have driven her car, with the other one following. If this scenario is even close to being accurate, then both she and her car could be 100 miles from Boonville in any direction, possibly even further. This would have transpired somewhere between 1:30 A. M. and 2 A.M., giving them 4 hours(+-) of darkness to drive wherever they wanted to go. They could have always driven back to Boonville after the sun came up. This scenario of course, would put the crime scene many many miles away from their stomping ground, the area they call home.
I still think the cops would be well advised to ask employers to contact them in regards to employees that came in super late on Friday, or didn't come in to work at all.
I think distributing flyers with pictures of her vehicle and a license plate number within a 50-100 mile radius would also be well advised.
I think a reasonable guess would be that her SUV headed AWAY from town, since it wasn't seen again on the video cameras. This would also make sense from the standpoint that the perps wouldn't want to go into the city street lights and traffic if they were in the process of abducting her. They would want to head into the darkest, out of the way path they could so as not to be recognized by anyone.
When they find the car, they will find her too.
