U.S. Department of Justice, Federal Bureau of Investigation

March 25, 2004

Mr. Stephen Koschal: On behalf of the FBI, I thank you for your assistance in the investigation and prosecution of forger Steve Lyons, one of the convicted subjects in the FBI's Operation Bullpen case.  The hours you spent working with Special Agent Timothy Fitzsimmons and Assistant United States Attorney Melanie Pierson were very helpful to the government's case. Your knowledge and professionalism resulted in Judge Jeffrey T. Miller accepting your trial testimony, after qualifying you as an expert witness in this matter. You should know that in the recent sentencing of Steve Lyons, Judge Miller singled out your expert testimony as very illuminating.  In describing the overwhelming evidence against Lyons, Miller noted that even without Lyon's recorded conversations, the government presented a clear case that was clarified through your testimony.  Judge Miller ultimately sentenced Lyons to 36 months in federal prison. I also want to thank you for your continuing assistance to law enforcement in combating memorabilia fraud. I know you have assisted SA Fitzsimmons, as well as other agencies, on other matters and I encourage you to continue in this worthwhile endeavor.

Signed: Kenneth W. Boschen, Supervisory Special Agent
