If a defendant is held beyond the time limit of this section and moves for dismissal, the criminal charge against the defendant must be dismissed.
If the defendant is not brought to trial within the ninety-day period, the criminal charges against the defendant must be dismissed with prejudice.
For purposes of this section, the evidence sought need not be essential or unique, nor is the state required to actually present such evidence at trial. However, if the state fails to make reasonable and diligent efforts to procure the evidence after the court grants the extension, the court may dismiss the criminal charges against the defendant with prejudice.
