Was Chechen immigrant Ibragim Todashev executed by the FBI?

Was Chechen immigrant Ibragim Todashev executed by the FBI? That's what his father, Abdul-Baki Todashev, said Thursday at a press conference in Moscow. He displayed 16 photographs he claims were taken in a Florida morgue that show his son had six gunshot wounds to his torso and one to the back of his head. The FBI says 27-year-old mixed martial arts fighter Ibragim was killed last week during an interrogation at hisapartment by one of its agents and two Massachusetts state troopers. They were questioning him about whether he had ties to slain Boston Marathon bombing suspect Tamerlan Tsarnaev,and about a 2011 triple murder in Massachusetts when he became violent, the FBI said. However, the Washington Post reported Wednesday that Todashev was, according to law enforcement officials, unarmed, which his father also asserts. "I'd only seen and heard things like that in the movies -- they shoot somebody and then a shot in the head to make sure," Todashev said. The FBI has refused to comment further since a brief statement Tuesday, saying the incident may be under investigation for months.
