Grandson got a Warrant issued for failure to appear

He should retain a criminal defense lawyer who can go to the Clerk's Office, review the court records, and compare that to what your grandson has to say to prepare to make the best presentation possible.  The bottom line is that since he has a warrant, your grandson needs to turn himself in. The best way to possibly do that is to have the lawyer file what is called a motion to quash the arrest warrant. In plain English, that means that it's a request for the judge to tear up the warrant and not take your grandson into custody.  Then, on that court date, the lawyer and your grandson appears so the argument can best be made to keep your grandson out of custody.  This should be done immediately. The longer your grandson waits, the worse his chances are of remaining out of custody.  Hope this helps.
