Inmates Charged in Prison Killings:  Four inmates serving time in the Pasquotank prison in North Carolina have been charged with the October 12 murders of two prison employees and injuries to ten others during a failed escape.  Ames Alexander and Gavin Off of the Charlotte Observer report that three of the charged inmates were serving sentences for murder or attempted murder while the fourth was a burglar due to be released next year.  As part of the escape plan, the inmates set a fire in the prison sewing plant, then attacked the employees with scissors and hammers.  Prison authorities believe that the inmates had planned to climb over a perimeter fence, but were interrupted by the rapid response of guards and local police.  Two of the injured employees are in critical condition.
