State of Tennessee v. Matt D. Polk

The Defendant, Matt D. Polk, was convicted of one count of the sale of 0.5 grams or more of cocaine and one count of the sale less of than 0.5 grams of cocaine. The Defendant received an effective sentence of twenty-five years. On appeal, the Defendant argues that a video recording was not properly authenticated and that the trial court erred in allowing an expert who had not been disclosed to the defense prior to the day of trial to testify. We conclude that the recording was properly authenticated and that the trial court did not abuse its discretion in permitting the testimony, and we affirm the judgments of the trial court.
