Inmates relegated to the SHU are sent there to segregate them from the general population for investigation of an incident or for punishment of a new charge. There is no set time that anyone on the outside could ever find out. This is all handled internally by the upper level management from the warden, to the associate warden to their captain and lieutenants. There is NOTHING anyone on the outside can do during this process, there are no legal representations or proceedings. There is a single Disciplinary Hearing Officer (DHO) that interviews the inmate and others associated with the incident and then makes a determination from their investigation.
