The bond change can represent several different things-- but without seeing the court's jacket, I can't give you a specific.  However, here are some of the things that could have happened.1.  His attorney could have made a motion for a bond reduction and the judge granted it for this charge only. 2.  It could mean that the prosecutor filed a motion to increase the bond and the "0.00" represents "no bond", or the revocation of the chance for any bond on this particular charge. 3.  It could also mean that he has entered a plea to the charge, is serving a sentence, and thus, there is no longer a bond option. The best way to know for sure is to look at the court's file or to call the jail administration department and simply ask them the significance of their notation of "0.00."  Every police department has it's own method for entering bond amounts.... so a phone call or review of the file is the only way to know for sure what the "0.00" means.
