That happened to us the same way. The rock was very large and went through the back window of our van and there were kids back there too but it missed them. We saw 3 kids on the overpass and called the cops and they ran away as soon as we stopped the car, the broken window was no doubt quite visible to those bastard kids. It made a hole in the window a good foot wide. I always wondered when someone would get killed that way.
