@Dot3 You've kind of gone a bit back and forth over the place a bit in this thread.
It sounds like from your latest posts:
The offending liar is no longer around and you don't know where he is.
You don't think you have any recourse against the school and don't want to go further.
You absolutely will not try to do anything to hold the family of the liar responsible
You now claim that you are pretty sure most of the town adults know the charges were lies???
You now claim that the harassment is coming from young people???
Due to family situations, moving is not an option for you anytime soon.
It also appears you aren't really one of the types that is of the "mess with my family I'll deal with your whole clan biblical style" types.
(I'm not saying that's a bad thing just it's a thing and determines your options).
So at this point it seems your only real options that you might be willing to peruse are to catch harassers in the act and peruse them criminally, civilly and with naming / shaming.
Check your laws very well and get yourself a lawyer who can do civil stuff as well as criminal stuff.
For example here in Texas if you slam on your brakes in front of someone for no good reason or in malice, you are at fault civilly and criminally for any accident that occurs.
On all your vehicles run front and rear dash cameras that are always recording.
Have cameras all around your house and on your fence line / mailbox to record all the time.
Make sure the cameras are of high enough quality that not only can you see that something happened, you can clearly identify to a jury who the person is.
(This is VERY important, that something happened is good enough for insurance, but if you go to court, you need to prove Who did it very clearly).
Have a setup for you and your wife to be able to record all interactions.
If you carry around a recent cell phone, most of them have belt clips available that leave the rear cameras facing outward & many smartwatches that link to the phone can start and stop the phone recording from your wrist.
EVERY time there is a harassment, follow up, track down who it is, (pretty easy with licence plates), for a small town pictures of people should be easily able to be researched etc. Then if it's a "Youth", tell your lawyer to invite them to come to their office to meet with you to see if you can avoid a lawsuit by having them promise to straighten out their kid. For adults have your lawyer send them a cease and desist letter promising a lawsuit next time.
If someone causes an accident or actually harms your wife or your family or affirmatively does actions to harm, threaten or impede them, have your lawyer get on it immediately & press charges as available.
You find someone saying something untrue, it's time for the lawyer to file a defamation lawsuit in the local court.
Eventually word will get around that you don't put up with any harassment and folks will probably eventually back off.
You might also wish to talk to your lawyer and demand a meeting with the local police chief and your lawyer and have it clearly explained to the police what is going on and that you will not be "just rolling over and taking it," and that you will hold them legally accountable if they fail to uphold the law.
All the above means you actually have to be willing to go the distance and follow through and put in the time, money and work.
But don't half ass things, you need to sit down with your wife and actually talk about what you are willing to do, and willing to stick to doing and put in the long term time / effort / money etc. You also need to find out what your wife needs to get to make her be able to hold her head high and feel vindicated and able to live her life in peace. (and sometimes nothing fixes that except some serious retribution, which you may not be able or willing to bring about).
