Recent Case Results
Helping Our Clients Achieve the Best Possible Outcome

  • Not Guilty Aggravated Murder

    In July of 2015, the Defendant was charged with the murder of a man in Springfield. After hiring our office, we worked hard with the Defendant and his family to prepare the best defense for our client. The trial lasted two days and resulted in a Not Guilty verdict on all charges by the Jury.

  • Conviction Vacated Appeal | State vs. K.M. (2nd District Court of Appeals)

    Client was charged, and later found guilty of, tampering with evidence kept by a government entity (F3). We appealed the case on the grounds that the trial court erred in not granting the client’s motion to dismiss stating that the statute of limitations had expired. In late 2018, the appellate court reversed the client’s judgement and vacated the client’s conviction.

  • Dismissed Civil Stalking Protection Order | Against our client

    Our client received paperwork that a Civil Stalking Protection Order was placed against our client. We challenged the protection order, asking for a directed verdict. The Judge agreed, stating that there was no threats of physical harm to the alleged victim and the mental distress evidence was not sufficient.

  • Case Dismissed OVI

    The Defendant was on the way back from a friend’s house when she was pulled over in her car for crossing over the marked lines. She was charged with an OVI. While waiting for her chance before the jury, the Defendant was granted driving privileges with the help of our office. At the Suppression Hearing, the OVI case was dismissed and the Defendant only had to pay court costs.

  • Acquitted Robbery (Physical Harm) F2 | State vs. J.M.

    Client was accused of robbing a local Rite Aid and charged with robbery while using/threatening to use physical harm. After 2 days of trial and 4 ½ hours of deliberation, a jury returned a not guilty verdict.

  • Not Guilty | Reduced Charge Sex Crime Charges

    The Defendant was charged with one count of attempted rape and one count of abduction. After multiple hearings with the prosecution and Judge, the case went to the Jury. When the trial concluded after two days, the Jury found the Defendant Not Guilty of attempted rape and Guilty of a lesser charge of unlawful restraint. He only had to serve 60 days which his jail time credit counted for.

  • Not Guilty Unlawful Restraint M3 | State vs. BV

    Client was accused of unlawful restraint while in her position in the health care field. Our client maintained her innocence throughout the case. After 2 days of trial, the jury returned a not guilty verdict.
