ANTIGO, WI (WTAQ) - Seven more people have been charged in a marijuana sales ring involving school teachers and others in Antigo and Merrill. That brings to 10 the total number who’ve been charged, and the investigation continues. All seven of the new defendants are due in Langlade County Circuit Court March 12th on misdemeanor counts of marijuana possession. Three of them have been on paid leave, after their names turned up in criminal complaints last month against three other defendants. The three are special education teacher Joseph Adams and learning disabilities teacher Mark Incha, both from Antigo High School – and Merrill middle school teacher Jay Peterson. The other newly-charged defendants are Anthony Crabb, Robert Hurlbert, Chris Nicholson, and Peter Miller. Two other Antigo school employees who were paid on leave have not been charged. The Antigo district says it’s still doing an internal investigation of all its employees on leave. The Merrill district has not commented. All the new defendants are in their 40’s-and-50’s. And prosecutors have said most bought their marijuana from Scot Peterson, who was charged last month with 26 counts. He’s due back in court March 19th, along with Brad Maahs of Wittenberg and former Antigo football coach and elementary principal John Lund. Lund was ordered yesterday to stand trial on eight felony charges, including marijuana possession and delivery and maintaining a drug trafficking place. Lund resigned last week.
