According to the indictment, Elfgeeh tried to arrange for three individuals to travel to Syria to join the extremist group in 2013 and early 2014. Authorities said two of those people were actually FBI informants.

Elfgeeh was arrested after federal authorities said he bought two handguns and two silencers as part of a plan to kill members of the U.S. armed forces returning from war and Shiites in the Rochester area.

The investigation included linking Elfgeeh’s home computer to tweets from alias Twitter accounts expressing support for al Qaeda, violent holy war and Sunni insurgent groups in Syria, according to court papers.
