A warrant is an order for a person to be brought before a court. Once in front of the court, he can make a plea. An attorney doesn't get to do that for him - he must make that statement with his own voice to the judge. That's why attorneys in Colorado are saying they can't help - because they can't...yet. They can give advice on pleading or not. They can assist in working deals in exchange for a plea. But this isn't going to be dealt with unless and until his fanny is actually before the judge IN the courtroom. His choices are to either (a) make plans to return to Colorado and start working with legal counsel to prepare to turn himself in and enter a plea, or (b) sit and wait at the mercy of the warrant, where he cannot predict when/where it will come into play, and wait to be arrested and for Colorado to bring him back on THEIR schedule (which could involve several weeks in jail just to get back).
You can check the Colorado Bar Association website for assistance in finding an attorney who specializes in criminal law.
