(Brookville, IN)--Franklin County Judge Steven Cox has been permanently banned from judicial service by the Indiana Supreme Court.  The action came Thursday and stemmed from a criminal case involving Gregory Guilfoyle, who shot his child’s mother and shot at a Franklin County deputy.  According to court documents, Judge Cox went to Guilfoyle’s home without the knowledge of prosecutors or defense attorneys to investigate the case himself.  Cox had served as a judge for 30 years and had also served as a special judge in some Wayne County cases.
