According to the International Herald Tribune, “One of the suspects [in Hrant Dink’s assasination], Yasin Hayal, an alleged Islamic militant who learned to make bombs from Chechen militants at a camp in Azerbaijan and who served 11 months in jail for the bombing of a McDonalds restaurant in Trabzon in 2004, is suspected of masterminding the attacks on both Dink and Father Santaro.”

The Turkish Haber Vitrini has an article on Yasin Hayal and a photo of him.
