One of the people died as the result of using the fentanyl provided by Grignon, and the other two were revived but sustained serious bodily injury as the result of using the fentanyl provided by Grignon.

The Menominee Tribal Police Department and Federal Bureau of Investigation investigated the case with assistance from the University of Wisconsin Hospital Pathology Department. Assistant United States Attorney Andrew J. Maier will prosecute the case in U.S. District Court in Green Bay.

 An indictment is only a charge and not evidence of guilt. The defendant is presumed innocent and is entitled to a fair trial at which the government must prove his guilt beyond a reasonable doubt.
