If I may be allowed to explain. The USB contains the location of several caches of weaponry to be used in the murders. Some of the campers know of this, including the victims, and have been working on it to locate all of them, including one that contains a nuclear weapon. Not all of them are on the USB, the nuclear one included, so Monokuma has given the person who has it as a motive for murder this case. So the killer is the person who currently possesses the USB key, and that's the person we are trying to find out. Is that a clear enough explanation of these events?
