I would start by looking at your retainer agreement with your current counsel to see his or her obligations. If they have ended and the public defender cannot take your case, you can interview attorneys to see who would be willing to be engaged for a flat fee "(one last nominal lump payment)". You should be able to retain competent counsel under a flat fee agreement.
If the warrant is Bondable, then yes, he should be able to post bond and be released. In Broward, as in all counties in Florida, the victim will have a say in the ultimate offer. Moreover, Restitution will almost certainly be part of any plea bargain. Having said that, typically, on a first offense Grand Theft, a Probation plea with restitution is offerred.
I actually went to trial on a case with very similar facts not to long ago. Thankfully, the Judge dismissed the case halfway through. As I see it, your first option is to have an attorney contact the Prosecutor's office (anything she says can be used against her) and see if they would consider not filing the charge. If they do file, you will then go through the legal process...but these facts are ripe for Pre-Trial Intervention, and/or defending at trial.
Law Enforcement is an occupation that is an exception to the confidentiality of Juvenile Records. Although you may have to track down the proper amount and where the money goes, it is never to late to pay the Restitution.
If this occurred in Broward, your best bet would be for an attorney to contact your Probation Officer to see whether a violation has been filed and a warrant signed by a Judge. A Judge may allow a surrender in court. Further, the State can be contacted to try to get a resolution to the violation before the warrant is even served.
Mr. Russo's answer is correct. In addition, if you did not know the clothes were stolen, and have evidence of same, that can be given to the State Attorney's Office, who have the ability to not file that charge.
It depends if the court requires a hearing or not. Some Judges require a hearing in court to hear the matter. This may take a little time to get on the court's docket. Others may review the matter in chambers and issue a written order.
Either way, I would suggest your attorney contact both Probation and the State to see if they can get an agreement before it goes before the Judge.
