Tuncay Güney and Ergenekon

Tuncay Güney, code name "Ipek" (silk), is a Turkish citizen of Jewish origin who claims to have infiltrated the Turkish Gendarmerie's intelligence organization JITEM, Ergenekon, the Workers' Party, and the Gülen movement before being outed. He is subordinate to Mehmet Eymür, who was discharged from the National Intelligence Organization (Turkish: Millî İstihbarat Teşkilâtı, MİT). The information Güney has gleaned on these organizations make him a key figure in the ongoing Ergenekon investigation. His statements form the backbone of the 2455-page Ergenekon indictment, which mentions him 492 times and labels him a suspect at large (Turkish: firari şüpheli).

Güney was born in the village of Gölet, Kargı, to Ali and Ayşe Güney; the youngest of three siblings. Güney says his family, whose roots can be traced to Egypt, was outcast by his community for being Sabbateans. Less than a year after his birth, they left for the Harmantepe neighborhood of Gültepe, İstanbul.

In his spare time, his mother teaches the Koran to her neighbors' children in Gültepe. Güney says it was normal for crypto-Jews to express their devoutness to Islam, such as by sending their children to seminaries, in order to be accepted.
