A Marion man is going to prison for 2 and a half years. Thirty year-old Shiloh S. Jackson entered a guilty plea to a charge of distribution of Fentanyl in December and went before a federal judge on Monday for sentencing. Jackson was ordered to spend two and one half years in prison and three years on supervised release. Jackson originally had charges that were drug related in Marion County, but were dismissed in July of last year after federal prosecutors decided to pursue charges in the case.
