Guandique denied attacking Levy. On November 28, the FBI had the informant take a polygraph test, which he failed. A polygraph test on Guandique, administered on February 4, 2002, returned inconclusive results that were officially ruled "not deceptive". Because neither the informant nor Guandique was fluent in English, D.C. chief detective Jack Barrett said that he would have preferred polygraph tests to have been administered by bilingual examiners, who were unavailable at the time. When Judge Noel Anketell Kramer was asked about Guandique's potential connection to the Levy homicide, she responded, "This is such a satellite issue. To me it doesn't have anything to do with this case." Kramer sentenced Guandique to 10 years in prison for his attacks on two other women at Rock Creek Park. Guandique was sent to the U.S. Penitentiary, Big Sandy near Inez, Kentucky, and was later transferred to the U.S. Penitentiary at Victorville, California.
