Fikri Mehmet Karadağ (born 3 January 1953) is a retired Turkish army colonel who was indicted for treason in the Ergenekon investigation for allegedly heading ultra-nationalist organizations called the Association for the Union of Patriotic Forces (Turkish: Vatansever Kuvvetler Güç Birliği Hareketi), and the Kuvayı Milliye Derneği (National Forces Society).
Garih was assassinated on 25 August 2001 by Yener Yermez, of the Hasdal barracks' café (Turkish: çay ocağı).
Also working in the café was lieutenant Murat Oğuz, who got caught in 2001 for petty fraud with the Ergenekon investigation's key figure, Tuncay Güney.
It is alleged that both Oğuz and Yermez were subordinate to Karadağ, in the capacity of Commander of the Mechanized Regiment (Turkish: Mekanize Alay Komutanı).
[2] Ergenekon suspect Oktay Yıldırım (whose grenades in Ümraniye launched the investigation) was also stationed in the Hasdal barracks.
