Yes, the district attorney's office in the county and state where you reside can still pursue a criminal action against a person that is more than two (2) years old (driving with a revoked driver's license) even though the arresting officer has been fired and has moved out of state.To puruse this action, the prosecution will be required to bring the arresting officer to the trial. If you do not have a criminal defense attorney for the situation you are in, you should retain one. Good luck.
