The trial court did not err by denying the defendant’s motion to exclude DNA evidence. The alleged crime occurred at a convenience store. An officer collected blood samples from the scene, including blood from cigarette cartons. The defendant argued that the cigarette cartons from which samples were taken should have been preserved. The court noted that the defendant did not argue any bad faith on the part of law enforcement officers, nor did he identify any irregularities in the collection or analysis of the samples that would call into question the results of the analysis. Therefore, the court concluded, the defendant failed to demonstrate any exculpatory value attached to the cigarette cartons from which the blood samples were collected.
