He should turn himself in and deal with it now. Otherwise it will haunt him until he is arrested. This is a unique situation which will require the input of his original attorney in California, and may require advice from an attorney in Florida. The arrest warrant will probably come from the court in California, and that state may choose to extradite him. It might be best to have an attorney here in Florida contact the probation officer to see if this matter can be resolved.
