According to some of the records documented within the storage device of Ring Lord Vanisher, a man-made virus to which only them had the cure was to be released in the city.
They would then capitalize on the fact that only they could make the cure.
The locations that had been destroyed were simply places the virus was being replicated and some other locations had also been rigged with them according to the records.
Even though Gustav's statement had not been taken yet since he hadn't fallen into the hands of the authorities, everything pointed to the fact that all these locations were destroyed for the preservation of the city.
Initial statements of some of the witnesses mentioned he was fighting off a group and even saved them so there were speculations that Gustav already found out about this ploy a long time ago and they tried to silence him.
