Legal Question in Criminal Law in California

Interstate flight to avoid prosecution is a separate federal crime.

Well, you could be charged additionally with flight to avoid prosecution. For you to handle this, you must turn yourself into the court, with or without an attorney, and try to negotiate a plea bargain on the warrant and outstanding charges. Doing so voluntarily will result in a better outcome than you being brought in cuffs to court after arrest on the warrant. That will happen if you come in contact with law enforcement or customs anywhere in the US. Effective plea-bargaining, using whatever legal defenses, facts and sympathies there may be, could possibly keep you out of jail/prison, or at least dramatically reduce it, and may enable you to get your probation and programs reinstated. If this is a felony, the defendant must be personally present at every court hearing and appearance. Unless you're competent to effectively represent yourself in court against a professional prosecutor trying to put you in jail, most people hire an attorney who can. If serious about hiring counsel to help you in this, and if this is in SoCal courts, feel free to contact me.
