A March 18 trial date has been set for 19 people accused of drug crimes while they were inmates at Mike Durfee State Prison in Springfield.
    
 All 19 defendants have pleaded not guilty. Bon Homme County Clerk of Court Heather Humphrey says they will stand trial as individuals, not as a group.
    
A grand jury indicted the suspects last month. The attorney general’s office says each faces two marijuana-related charges that together carry a maximum punishment of three years in prison.
