How can I get a criminal case moved to another county

If you are the victim, you aren't on "trial" (although it may feel that way). A victim of a criminal offense is generally not a plaintiff or defendant or any other party in the case. Not being a party, the victim generally has no standing to challenging where the trial is held. As a victim, you can express your opinions to the prosecutor who may or may not listen to what you have to say. If you are actually a defendant, you can review your concerns with your attorney. If there are issues of too much pre-trial publicity or other issues, your attorney can ask the court to consider moving the trial somewhere else.

If I read your question right, are you saying that you are the defendant and therefore, are you are stating that you are wrongfully being charged? If that is the case, and you feel that the criminal charges against you will not enable you to receive a fair trial, you need to speak with your attorney and have them file a motion for a change of venue. They are not readily granted, but, if you have some specific reasons, you need to speak with counsel and express your concerns. If you are the victim in the case, generally the person accused is the one who will seek a change of venue. Good luck.
