Special Agent Matthew White and other agents with the United States Bureau of Alcohol, Tobacco, and Firearms (ATF) went to the apartment of Aaron Jackson (defendant) and asked him whether he had any firearms or ammunition. Jackson showed the agents a safe containing a quantity of ammunition, which was seized by the agents. The United States (plaintiff) charged Jackson with possession of ammunition by a convicted felon in violation of federal law. At trial, the government entered a certified copy of a 1984 judgment entered in a New York City court showing a person named Aaron Jackson being convicted of unlawful possession of a weapon and of a controlled substance. No other evidence connecting Jackson to the 1984 conviction was presented. Jackson did not present any witnesses or testify in his defense. During closing arguments, defense counsel argued that the government failed to prove that Jackson was the same individual named in the 1984 judgment. Jackson was found guilty. He appealed, arguing that the government failed to prove beyond a reasonable doubt that he was the same individual as the one named in the 1984 judgment.
