Van Pickerill turned out to be integral to the prosecution’s case, and as much as he apparently told federal investigators, I was surprised to find that there were no statements made by him within the investigative notes. There was one document that I originally dismissed as insignificant but which does confirm that he made at least one statement to U.S. Attorney Slack. There was one problem with it though—-it went missing. Were Pickerill’s statements intentionally sanitized from the investigative notes to shield Mayor Bosse from prosecution?
