Abdullah Çatlı was a Turkish secret government agent, as well as a contract killer for the National Intelligence Organization (MİT). He led the Grey Wolves, the youth branch of the Nationalist Movement Party (MHP), during the 1970s. His death in the Susurluk car crash, while travelling in a car with state officials, revealed the depth of the state's complicity in organized crime in what became known as the Susurluk scandal. He was a hitman for the state, and was involved in the killings of suspected members of the Kurdistan Workers' Party (PKK) and the Armenian Secret Army for the Liberation of Armenia (ASALA).

The Grey Wolves, officially known by the short name Idealist Hearths, is a Turkish far-right political movement and the youth wing of the Nationalist Movement Party (MHP). Commonly described as ultra-nationalist, neo-fascist, Islamo-nationalist, and racist, it is a youth organization that has been characterized as the MHP's paramilitary or militant wing during the political violence in Turkey. Its members deny its political nature and claim it to be a cultural and educational foundation, as per its full official name: Idealist Clubs Educational and Cultural Foundation.
