Before he was said to have tortured terrorist suspects at Guantánamo Bay, Det. Richard Zuley allegedly did it to criminal suspects in Chicago. An investigation by The Guardian found that from 1977 to 2007, Zuley used harsh methods to gain confessions, including at least one that led to a wrongful conviction: Lathierial Boyd, who was sentenced to 23 years in prison before being released on the basis of faulty police work. In a new lawsuit, Boyd claims Zuley planted evidence, withheld crucial details, and was racist. Three others, who are still in prison, underwent Gitmo-like techniques, including “prolonged shackling, threats about family, pressure to confess,” according to The Guardian. That’s what Zuley allegedly used on Mohamedou Ould Slahi in 2003 at Gitmo when the detective, also a Navy reserve officer, was put in charge of his interrogation. Under Zuley, Slahi was subjected to death threats, extreme temperatures, and sleep deprivation.
