Fortunately, since there's no evidence, no one was deported. Instead:

One family essentially swept the incident under the rug by paying off the damages, declaring what actually happened to be impossible to discern the truth of; both accusers start trying to get closer to the commoner, not leaving her alone.
One girl is punished by cleaning the school, although another would help clean and yet another would help pay for the damages.

The commoner seems to be discouraged from going to school, entirely avoiding the rest of the semester. Her parent seems to be trying to get a sports class going at school, but they need everyone's support in order to be able to proceed.

The semester passes without further incident, but . . . !?

On the first day of the new semester, the stolen possessions show up in the lockers of three different girls: were they the culprits after all. . . !?!?!

So now the tables are turned and you're being accused of wrongdoing and, uh -

Well, your daughter doing all this "organizing" and "neighbourhood watching" isn't really doing much to help anyone think she isn't the culprit.

What do you do about this?
