“Hello Doug:

This is Joe Oesterling checking in. Yes, the trial is over, and the jury’s verdict is “not guilty”on all seven counts. For my wife, Carmen, and I, this is great news. As you can imagine, this is a tremendous relief for both of us.  I also want to thank you for the work that you have done and your testimony during the trial. You clearly brought some common sense to the crazy financial numbers the prosecution and DEA we’re trying to show.
