I didnt have access to a weapon. Reporter a local ballistics expert said by studying physical evidence found after shootings the police can rule out several firearms and start from there. The investigators are being very cautious as they should. Reporter investigators say determining after testfiring several guns, bullet fragments matched a gun. As long its not fired thousands of time between the incident and the time its collected it should be pretty easy to match. Reporter but merritt has maintained that the gun has been at the pawnshop for at least two months. If he committed a gun, he has more sense to pawn said firearm because it links directly back to you.
