You'll probably hate to hear this, but in some instances you simply have to cut your losses.  Judgements are only worth it when you can collect.  And this is a situation where that may not be possible. You would have to track the people down.  If they're in different states, you'll be required to record the judgment in that state's public records.  You'll then have to take depositions in aid of executing the judgment.  This is a process that would cost you thousands of dollars-- it simply may not be worth it.
