If this is a collection agency then it normally is illegal to tell your relatives (a "third party") that you allegedly wrote a bad check. All the collection agency can do is ask for your "location information" which is:
1. Your home address;
2. Your home phone; and
3. Your place of employment.
I doubt this is the court or the police.
If it is a collection agency then normally you will have protection under the Fair Debt Collection Practices Act (FDCPA) which is a very powerful law that keeps collectors from mistreating you like this. Or if they do mistreat you, you have the ability to sue and collect money damages if you are successful and force the collection agency to pay for your legal fees.
Let me know if you find out more information about this out of state place.

It's not unusual for a police department to follow up on a bad check issue. Try "googling" the phone number to see what you find; or in the alternative leave a message for them and see what facts they are able to establish about this check issue. From there, you will be better prepared to resolve the issue.
It is unlikely that the court is trying to contact you. More likely it is a collection agency.
There may be statute of limitations issues and you could possibly file Bankruptcy to stop the collection effort.
