1. The defendant was convicted of possession of a handgun with an altered serial number. The defendant contended that he did not know the serial number had been altered. The prosecution offered evidence that the gun was "shiny" in the location of the serial number. The prosecution also proved that the defendant was in possession of the handgun for a week. Is this sufficient evidence to prove beyond a reasonable doubt that the defendant knew the serial number had been altered?
