According to the criminal complaint against the three, the FBI first began investigating Juraboev after he made postings on Uzbek-language social media sites in August 2014 praising the Islamic State and offering to pledge allegiance to them. While these postings were made anonymously, Juraboev neglected to conceal his IP address which led to him being quickly identified by authorities.

On Aug. 15, 2014, Juraboev was visited at a Brooklyn residence by FBI agents; he openly expressed his desire to join Islamic State to them. He is said to have told the agents he desired to travel and join the group, but that “he currently lacked the means to go there.”
