In a murder case involving a shooting, the trial court did not commit plain error by allowing a Special Agent with the State Bureau of Investigation to testify as an expert in the field of bullet identification, when his testimony was based on sufficiently reliable methods of proof in the area of bullet identification, he was qualified as an expert in that area, and the testimony was relevant. The trial court was not required to make a formal finding as to a witness’ qualification to testify as an expert because such a finding is implicit in the court's admission of the testimony in question.
