Another step is taken in the battle against opioid use and, all too often, what ends up being an overdose death investigation and the subsequent prosecution. Missouri Attorney General Josh Hawley teamed up this week with the Office of Prosecution Services and the National Attorneys General Research Institute to sponsor a day-long training course on the subject. The course focused on issues related to the investigation and prosecution of death cases from overdoses of heroin and fentanyl. Several national and local speakers participated in the training. Local law enforcement agencies and prosecutors from across the state were represented during the training.
