Justice has to be served and it was. Those are the words of Assistant U.S. Attorney John Bennett after former Bethel Police Lieutenant Jerome Cox entered a guilty plea Tuesday afternoon on a cocaine trafficking charge. Bennett is prosecuting the case against Cox and former Bethel Police Chief Reginald Roberts, also charged with trafficking cocaine and for selling a firearm to a convicted felon. Bennett says part of Cox's plea agreement could require him to testify against Roberts. Cox also waived his right to indictment by a grand jury, meaning his case can go straight to a sentencing hearing which is scheduled for early April. At Tuesday's court proceedings Cox was ordered back in custody and will be held behind bars at the Pitt County Detention Center until his sentencing. Reginald Robert's arraignment is scheduled for February 13.
