In this felon in possession of a firearm case, the defendant failed to submit an adequate record on appeal to support his challenge to the unanimity of the jury verdict. A juror entered the courtroom during the jury charge conference on a flight instruction. The defendant argued that because the juror possibly became privy to information outside of the presence of the other jurors, his right to a unanimous jury verdict was violated. The court declined to consider this issue because the defendant failed to provide a sufficient record to allow meaningful appellate review. The transcript is devoid of any information beyond the juror’s entrance into the courtroom during the charge conference. It is silent as to whether the juror proceeded past the courtroom door. The trial court’s statement, as indicated in the record, suggests that the juror immediately exited the courtroom, as did the fact that the charge conference continued. The defendant did not submit a supplemental narrative to provide context for the alleged error. Review of this matter would require speculation as to the length of time the juror was in the courtroom and information he or she might have overheard. There is a long-standing presumption in favor of regularity, with the burden on the appellant to show error. Here, the defendant did not produce any evidence overcoming that presumption.
