As I was driving 55 mph on a us route (no overpasses in the area), I heard what sounded like a gun shot and then the glass of my sunroof shattering. The interior shade was closed so I could not see the damage immediately. When I pulled off the road there was a large hole in the center of the sunroof glass and the glass was raised upwards as though it had been impacted from an object thrown from inside the vehicle. There was no evidence of any object that might have impacted it from the outside.
