I'm starting to think the theory about the automotive shop nearby being part of this mystery may hold some weight. Someone with a pretty good knowledge of vehicles would know about the speed sensor and how to disable it in a hurry. If she had taken her car there to get it worked on in the past, the mechanic would
certainly know that it was rigged up that way. Like I stated this morning, simply taking the battery cable off the positive terminal would kill all the electronics in the vehicle, and it would also allow someone time to completely disable or disconnect the speed sensor. After which, the battery cable could be reconnected and the car driven anywhere in the world without worrying about the tracking software.
I hope they are pursuing that possibility, because it does seem to make a lot of pieces of the puzzle fit together a lot better. Also, what better place to hide a vehicle than in an enclosed building , even if for just a few hours ? It was a Sunday, shop would have been closed.
There was a case about a year or two ago that had similar details: Girl works at an auto repair shop, showed up after a high school graduation around 9 p.m., vanishes. It was later discovered that she had been killed at the shop, and then taken and buried on private property. There were three different men being held for it. To this day, the exact motive is unclear as to what triggered it. Her name was Leah Martin. case here:
