I believe that there never was a vehicle involved. I truly believe that MPD never actually saw a car in a corner of a frame of a video from in the church at least from the video we have seen and knowing the layout and structure of the church. I believe they misinterpreted what they were seeing in one of the camera views when they were actually looking at a golf cart that is parked on the Northwest entry.I'm with you on many of your points. Are you of the opinion the Altima seen on SWFA camera is most likely involved? In your scenario of SP leaving on foot, approx 100-150 ft off church property, what is your best guess on SP exiting the church, the church grounds, and mode of getaway once off church property?
As for the Altima, my original line of thought at the time was that it was released to the public not so much as a lead requiring public help but as a message to SP. However, not too long after this I came across in Street View an Altima that matches that description parked next to a walled in dumpster area in an out of the way part of the parking lot where my POI(s) work. I tipped this particular vehicle even though the Street View image was old because it may have belonged to them. My current thinking on the Altima is unchanged. If it had any involvement whatsoever I would expect it to be part of the obfuscation and subterfuge - that is, it was meant to be seen where it was seen when it was seen. It is very possible that the Altima has nothing to do with this and it is just coincidental that an Altima matching the description could be seen where I found it.
