Conners Thomas B. Heffelfinger Best & Flanagan LLP 60 South Sixth Street, Suite 2700 Minneapolis, Minnesota 55402 Re: Dr. Michael Schulenberg Dear Ms. Conners: I am writing to inform you and your client, Dr. Michael Schulenberg, of the U.S . Attorney's Office intentions with respect to an issue that you have raised in connection with the civil settlement of claims under the Controlled Substances Act against Dr. Schulenberg. You have requested that the Criminal Division of the U.S . Attorney's Office clarify its intentions with respect to Dr. Schulenberg. I understand his concern to be whether, in the view of this office, he is currently the target of a criminal investigation. In the context of a criminal investigation, a "target" is a person who is linked by substantial evidence to the commission of a crime and who, in the prosecutor's judgment, is likely to be charged. At this time, Dr. Schulenberg is not a target of any criminal investigation. Other than the matters set forth in this letter, this office has made no other representations or promises to you concerning this matter. Very truly yours , GREGORY G. BROOKER By: . HOMPSON S .
