The GBI has launched a criminal investigation against the Murray County Chief Magistrate Judge who resigned on Wednesday amid allegations of wrong doing. Bryant Cochran is accused of pre-signing blank arrest warrants for local law officers and propositioning females who came before his court, for sex. GBI Director Vernon Keenan said the matter contained very serious allegations against Cochran. Cochran issues a statement accepting responsibility for the pre=signed warrants that were left for officers to fill out when he was not around. The Judicial Qualifications Commission asked the GBI to  join the investigation.
