You should surrender to authorities. It will be better for you that you turned yourself in. Work toward preserving the deferred. You will be grateful in the long run to have the matter expunged from your criminal record
Be prepared to argue that you should be held in contempt of court instead of having your probation revoked. Some time in jail is a small consequence to having a theft conviction on your permanent record. Hire a lawyer to help you stay on probation and keep the deferred.
I'm going to differ a little from my colleagues. Go engage a lawyer BEFORE you turn yourself in. She may be able to negotiate exactly what you want. The one thing you and the state can agree on is that you were not a delightful probationer.
If you pay the amount owing or have cash bond in amount owing you might be released.
If you have money owing and a paid attorney you might save your deferred.
Otherwise , you are likely to sit in jail.
There are customary ways to handle these cases. Any good local attorney knows them. You haven't asked for community service. You have absconded for an unidentified time. What do you think the court will do- treat you more favorably than the persons who paid their fine and did what they were supposed to do when they were supposed to do it? Hire an attorney.
