Plan B
The next day everything was back to normal, as if nothing had happened, they had at least expected something to come from all of this. Of course the students still gossiped about the events that happened behind the second year building, but because nobody really knew what happened that's all it was, rumours. The scene of the murder had been cleaned up quickly after the investigation had finished, and the second year students were allowed to enter their building again.
The rumours kept spreading between the students, one story was wilder than the next, so eventually the Generals decided to send out a general announcement to update all the students about the situation. They did this to avoid that rumours would turn into panic. So all the students were sent an emergency announcement through their wrist watch, everyone got the same voice message.
