During the day, the prison barracks were empty since most prisoners worked on the fields. At night, the two free world employees patrolled the central corridor but did not venture into the barrack units. The trustees, armed with knives, kept the order at night. Some inmates, referred to as "crawlers" and "creepers," stabbed sleeping prisoners. Male on male rape frequently occurred in the housing units. The prison did not ask trustees to intervene in case of rape, and prison guards rarely intervened.
