Michael Zomber, a highly respected gun collector and historian, was convicted in 2003 of conspiracy to commit mail and wire fraud by significantly overcharging Joseph Murphy, a millionaire businessman and firearms collector, for several guns. Zomber was sentenced to 30 months in prison. After his trial, it was revealed that prosecutors failed to disclose a letter that Murphy had written to Bill Gates, offering to sell the guns for the same price Murphy had paid for them – which contradicted Murphy’s testimony that he paid more for the guns than he thought they were worth. In November 2008, the United States Court of Appeals for the Third Circuit overturned Zomber’s conviction and ordered a new trial. The prosecution dropped the charges in July 2009 after Zomber agreed not to seek compensation for prosecutorial misconduct under the Hyde Amendment.
