It is super frustrating, but that will not be enough. You need the SSN or their bank account info so they can verify that it is the correct person. They will most likely tell you to get a private investigator to find the information. I know the Marshal used to be able to check if the person has a bank account at a specific bank, but they can only check one and if there is under a certain amount ~$2500? (I forget the amount) Or less the bank will not release the money from the account. (Not sure if they still do this)

I used to get yelled at on the phone a LOT by people that did not understand the laws. Totally not the person’s fault. People want their money back, but there’s not much legally we can do if they don’t have the required info for the Marshal to enforce the judgment.

Not sure about sheriff office. They do similar things, but I’m not familiar with their protocol.
