Abreu (defendant) was charged with crimes relating to his possession of a shotgun. The shotgun was seized by Special Agent Brian Glynn, who identified the shotgun at trial based on the evidence tag on the gun and by testifying that it was in substantially the same condition as when he seized it. Special Agent Glynn could not find the serial number, and he inaccurately described the firearm as an S.S. Christy even though it was an S.S. Kresge shotgun. Two other law enforcement officers involved in the investigation after Abreu’s arrest also identified the shotgun during their testimony at trial, and both of them found the serial number on the gun, correctly called it an S.S. Kresge, and testified to establish the chain of custody of the shotgun from seizure to trial. Abreu appealed his conviction, arguing that the chain of custody was not established, because of Special Agent Glynn’s incorrect identification of the type of shotgun.
