In a murder case, the trial court did not err by admitting testimony concerning nine-millimeter ammunition and a gun found at the defendant’s house. Evidence concerning the ammunition was relevant because it tended to link the defendant to the scene of the crime, where eleven shell casings of the same brand and caliber were found, thus allowing the jury to infer that the defendant was the perpetrator. The trial court had ruled that evidence of the gun—which was not the murder weapon—was inadmissible and the State complied with this ruling on direct. However, in order to dispel any suggestion that the defendant possessed the nine-millimeter gun used in the shooting, the defendant elicited testimony that a nine-millimeter gun found in his house, in which the nine-millimeter ammunition was found, was not the murder weapon. The court held that the defendant could not challenge the admission of testimony that he first elicited.
