Kayla Mueller

Last summer, U.S. forces conducted a raid in Syria that resulted in the capture of Umm Sayyaf, an ISIL member involved in the imprisonment and rape of women including American citizen Kayla Mueller. She was in U.S. military custody long enough to allow for interrogation both by the HIG and by a subsequent FBI clean team, but was not ultimately brought to the United States for trial. Instead, she was transferred to Kurdish authorities to face trial there.
