Amid the investigation, court records show, Greene fell in love with Cuspert, sneaked off to Syria in the summer of 2014, married him and warned him that "the FBI had an open investigation into his activities." She quickly became disenchanted — e-mailing an unnamed person that she had "made a mess of things" — and somehow managed to escape Syria and get back to the U.S., where she was arrested.
On June 11, 2014, Greene told an FBI supervisor in Indianapolis that she was traveling to Germany to see her family. She filled out the required form and listed "vacation/personal" as the reason for going. Her declared return date: July 4, 2014.
