ST. PAUL — An attorney for victims of clergy sex abuse wants Gov. Mark Dayton to convene grand juries to investigate alleged cover-ups by Catholic bishops in Minnesota.

Attorney Jeff Anderson said Wednesday he was inspired by a grand jury investigation in Pennsylvania that showed about 300 priests in the state had molested more than 1,000 children.

According to a press release, Anderson said the Dioceses of Crookston, St. Cloud and Duluth have not released their files on abusive priests and that they are “holding onto their secrets.” All three dioceses have filed for bankruptcy or announced plans to do so.

But Minnesota’s statutes on grand juries said nothing about governors having the power to call grand juries. That power resides with county attorneys and district judges.
