Authorities say a man serving time for killing a woman has hanged himself in his cell at the Louisiana State Penitentiary.
   West Feliciana Parish Sheriff J. Austin Daniel tells The Advocate (http://bit.ly/SPRCAp ) that 26-year-old Dustin Pleasant hanged himself Friday with a blanket.
   Pleasant had walked away from a work-release program near Lake Charles, Daniel said, while serving an eight-year sentence for aggravated assault on a peace officer.
   On Nov. 30, while he was on the loose, Pleasant allegedly killed Brittany Grosse, a co-worker at a sports grill in Lake Charles.
