While I realize this will likely be going against the grain of popular opinion on this case (robbery scenario), I, personally, think it is either Mr. or Mrs. McCann driving their car "slowly" around Prince George, and meandering the highways, "unaware" that LE is even looking for him/them. I am implying/speculating some sort of state of delusion here, and it purely speculation on my part.
This could explain why LE is sending plainclothes officers to search for the vehicle (the fact that Mr. and/or Mrs. McCann are unaware LE is looking for them).
Why would a thief be driving the McCann's vehicle "slowly" around town?
Also, I have seen discrepancies on the last reported use of the credit card. One news outlet says July 3rd at the Gas Station in St.Albert, another says July 5th. Which is it?
I hope that the McCann's are safe. I just have this feeling like things are not as they appear.
