The Google search: "Shawanna Nelson" arkansas site:gov gets 2 hits, including a Department of State report: The United States' Response to the Questions Asked by the Committee Against Torture, Geneva, Switzerland May 8, 2006 which states:
"Allegations of the misuse of shackles or other restraints in both federal and state prisons are investigated by the Department of Justice, and may be the subject of civil litigation in U.S. courts. For example, there is pending private litigation in Arkansas in the case of Shawanna Nelson. While the federal government is not involved in that case, following reports of this incident, the Department of Justice conducted an inquiry at the facility and asked the inmates about any other occurrences, and none were reported. We currently have a private Memorandum of Agreement to monitor the facility where Ms. Nelson had been held in Arkansas to make certain that no unconstitutional conditions exist for the inmates."
The other hit is a schedule of hearings from U.S. Court of Appeals, 8th Circuit which lists: DIVISION III 27th Floor Northeast Courtroom FRIDAY, MARCH 14, 2008, BEGINNING AT 8:30 A.M. BEFORE JUDGES RILEY, GRUENDER, SHEPHERD1. 07-2481EA Shawanna Nelson v. Larry Norris, etc., et al. 15 [seems to be 15 min. allotted for the Counsel's oral argument]. Larry B. Norris is the current Director of the Arkansas Dept of Corrections, per his message on their website.
