I agree with the previous post regarding the possible range of punishment for the theft charged described. The actual punishment would depend on the plea bargain. If there are no prior felonies the punishment would likely be a deferred adjudication.
You should hire an attorney and speak with a bondsman. You have to be prepared to make a bond when the charges are filed. If the total amount is $2,500, the charge will likely be a State Jail Felony of Theft. Like the previous posts explained, you will likely be required to pay back the money and possibly have the charge reduced to a misdemeanor or receive a deferred adjudication.
In regards to the ticket, if you did not appear, you can either make a bond or pay the fine. You should do something because this will eventually catch up with you. You do not want to get stopped for a traffic ticket in the future and have an outstanding warrant that will result in your arrest.
As to the surcharge you should contact DPS to set up a payment plan. If you do not pay your surcharge your license will remain suspended.
The new case can have a trial date, however, hearing for the Motion to Revoke can occur before the trial. It is possible to first lose the Motion to Revoke hearing and be sentenced to prison and then win at trial. The standard of proof for the Motion to Revoke is a lower standard than the beyond a reasonable doubt standard for trial.
Your boyfriend needs to speak with his attorney so that he has a clear understanding of what he is facing.
I am assuming you filed a motion for probation prior to trial as the rules require. That has no bearing on your right to appeal. You have 30 days to file a motion for a new trial. You need to contact an attorney immediately to assist you in this process.
I agree with the previous responses. Your case will not be dismissed as a result of being released because the county where the warrant originated failed to pick you up. You need to hire an attorney in the county where the warrant exists to address this issue.
