With a focus on Detroit’s 9th precinct, which has historically experienced the highest levels of violent crime in the city, the Wayne County Prosecutor's Office (WCPO) is attacking the problem from multiple angles. First, it developed a dedicated NFS team, which responds to all NFS incidents in the 9th precinct and handles these cases from start to finish. The project also utilizes a one-man grand jury, comprised of a circuit judge, who has broad powers to investigate criminal activity. The statutorily-created one-man grand jury process supplants the need for an investigative subpoena, complaint and warrant, and preliminary examination. The streamlined nature of the process speeds up investigations, reducing opportunities for offenders and their allies to intimidate victims and witnesses. The secrecy of the grand jury proceedings also ensures that witnesses can speak freely without fear that their testimony will be made public. Dr. Ed McGarrell and a team of researchers from Michigan State University are now examining the impact of the IPS initiative on case closures and violent crime rates. Early findings suggest that WCPO’s strategies in the 9th precinct have led to increased case closure rates as compared to other Detroit precincts.
