In 2014 it was reported that he was called into service and assigned to the Guantánamo Bay detention camp in 2003, where as a lieutenant he led the interrogation of Mohamedou Ould Slahi, classified as a high-profile detainee.
[7] Since the 1990s, the Police Department, city of Chicago and Cook County have been dealing with multiple investigations of officers accused of having tortured suspects to gain confessions.
Under Cook County State's Attorney Anita Alvarez, the Conviction Integrity Unit in 2015 planned to subpoena Zuley's entire complaint history.
In addition to making direct payments, it provides for psychological counseling for victims and their families, free classes at the city college for children and grandchildren, and other services.
[4] One of his subjects, Lathierial Boyd, was freed in 2013 after Cook County State's Attorney Anita Alvarez reviewed his case when new evidence was introduced; her office dropped all charges against him and said he should never have been prosecuted.
[8] In late 2002 Zuley was called into service in the Naval Reserve to serve as an interrogator at the Guantanamo detainee camp established by President George W. Bush.
[3][9] Salahi was one of a small number of high-profile Guantanamo captives for whom the Secretary of Defense authorized the use of so-called extended interrogation techniques; legal scholars and human rights critics have since characterized these methods as torture.
On February 18, 2015, Spencer Ackerman, reporting in a two-part series in The Guardian, covered Zuley's alleged involvement in the torture and forced confessions of several homicide suspects in Chicago.
These included being "force-fed seawater, sexually molested, subjected to a mock execution and repeatedly beaten, kicked and smashed across the face, all spiced with threats that his mother will be brought to Guantánamo and gang-raped.
Ackerman based his account in part on the Senate Intelligence Committee report on CIA torture, which had quoted from Zuley's memos at Guantanamo.
[12] Reportedly Zuley wanted to blindfold Slahi, load him on a plane, take him on a long flight circling Guantanamo, but tell him, when he landed, that he was in an Arab country allied to the US, where even more brutal torture was routine.
