Me too. I would say that lots more people have thought about leaving their lives than people would guess. But...I don't know how they would actually go about it, especially someone like Susan (or myself). Actually doing it is and staying away and hidden can't be simple.
And for what purpose would "staging the scene" to look like it does, benefit Susan? Susan could have just vanished in her car, or took a bus with her ID, etc. Why leave the ID? Why leave the car? Why make it look like something other than it is?
If somebody did harm to Susan, why drop the ID near where the car is?
If the perp was looking for money or items, why not burglarize the home as well, seeing as Susan lives in the neighborhood. They have(had) her ID which gives the physical address of her home. The registration to her unlocked car gives the physical address to her home.
The perp did not want or need Susan's car.
What purpose would staging the scene to look like it does, benefit the perp?
They didn't want or need her ID, they didn't want or need her car.
The credit cards are gone (But NOT used), and some cash gone.
And the most important of all the Valuables is Susan; she is gone.
Certainly, dropping her wallet where it was found, would guarantee that someone would find it.
Dropping the wallet where it was found, if there were cameras, could then view who dropped it, if they physically walked there.
Was the wallet thrown from a car?
Why is there No known video of Susan being at the shopping center or even near the area? There was discussion of going through video to discern if Susan was there (her car was there), but yet after Two Months, No video is being released.
What is on the video that LE does not want released? Who is not on the video?
