In a prosecution on three counts of mail fraud and one count of aggravated identity theft, the convictions are affirmed, where: 1) there was sufficient evidence to convict on the identity theft count, as the combination of the birth certificate and the credit reports the defendant possessed was sufficient to allow a rational finder of fact to conclude that the defendant knew that the person whose birth certificate she possessed was in fact a real person; and 2) the defendant did not show that she was in any way prejudiced by her attorney's performance as trial counsel.
