Detention warrants stem from new evidence and findings in the investigation according to reports. Nine suspects have been charged by the prosecutor with being accessories to murder, forgery in and destruction of official documents and abuse of duty. Dink, then editor-in-chief of the Armenian Agos newspaper, was shot dead by a teenager on Jan. 19, 2007 outside his office in Istanbul. Dink drew the ire of hardline Turkish nationalists in his lifetime, as he was one of the most outspoken voices calling for a debate to start on the controversial Armenian genocide issue. He received numerous death threats before his murder and faced several lawsuits for "denigrating Turkishness," an act punishable with prison terms, for his articles and editorials on the mass deaths of Armenians in 1915.
