Rear window shattered

[Riff Raff]

Note to self dont drive by that town. Sorry to hear.

x2. Hmmm; St. Louis, MO. So noted and forever black-balled from my GPS.

Things that come to mind as a possible cause (besides beng shot at) is perhaps the rear defroster was turned on in frigid cold weather and caused it to shatter. Another possible idea may be that the rear door hinges are loose and when traveling over a hefty bump caused the window frame to be tweaked and caused the breakage. If not, then it must be Gremlins.
