A: If the person entered a plea without an agreed recommendation, then the person opens himself up for the full range of punishment. The decision rest solely on the judge. I am guessing that is what happened in this case. However, if the plea papers indicated an agreement with the prosecutor, then the judge will always indicate whether he or she will be following the recommendation. If the judge decides that he or she is not accepting the agreement of the parties, then the defendant has the option to withdraw the plea of guilty. You might want to speak with his defense attorney to get some clarification.
A: Yes, if you took a deferred adjudication. It will come up on a background check. It will show that it was dismissed and that it is not a final conviction. You will have to apply for a non-disclosure in order to be able to hide the crime from any non government agencies. Speak to a criminal defense attorney or learn how to do it yourself. Good luck.
A: Yes, you can be arrested for a warrant that you did not know about. It happens all of the time. Arrest are not always made immediately by the police. A burglary where the suspects where not caught on the scene is a great example. The police investigate and try to determine who did it and when they find out who they think did it, warrants are issued. Just because a warrant was issued, does not mean that your boyfriend is guilty, they just think he is the guy that was involved in the crime. The police do make mistakes and the wrong person can get charged. I would also second the advice given by attorney Locke. Good luck.
