(Fargo, ND) --  Federal prosecutors are seeking access to some confidential materials connected to the Alfonso Rodriguez case.  The U.S. Attorney's office wants a federal judge to allow the review of certain motions, orders, proceedings and reports filed by Rodriguez's trial attorneys.  They say the materials will help them respond to claims that former defense attorneys failed to introduce evidence about Dru Sjodin's manner of death -- and Rodriguez's mental capacity and life history.  Rodriguez is on death row at a federal penitentiary in Indiana.  His new attorneys claim Rodriguez is not mentally competent to be put to death.
