First of all, we can safely rule out any theory of a shot from close range, from the side, or from behind. Furthermore, we must bear in mind that in this calculation, a few milliseconds can shift the result. In this respect, the roof on which a suspicious person was spotted is very well located in the narrow area that is not excluded by any microphone as a “blind spot” and in which the lines for the calculated shooter positions intersect or converge at a bullet velocity of about vb=800m/s. However, it must also be said that the result converges more strongly at vb=900m/s, indicating a location a few meters to the southwest of that roof. As far as can be judged from a distance, a shot from a window at this location would have been possible.
