Updating a story we’ve been following all fall and winter, a southwestern Illinois man is scheduled to be sentenced for his role in a drug-trafficking ring prosecutors say also involved a judge who later resigned after being accused of heroin possession.  Sean McGilvery pleaded guilty in October to felony heroin conspiracy and possession charges in U.S. District Court in East Saint Louis.  That’s where he’s set to be sentenced today.   Federal prosecutors say former St. Clair County judge Michael Cook was one of McGilvery’s regular customers while he was on the bench.  Cook was arrested last year as part of an investigation that also focused on the cocaine-related death of a prosecutor-turned-judge at the Cook family’s hunting cabin.  Cook has pleaded guilty to federal heroin and weapons possession counts.  He is scheduled to be sentenced February 26th.
