One of the most intriguing mysteries surrounding the Boston bombings was the identity of "Misha," the man who allegedly "brainwashed" Tamerlan Tsarnaev, in the words of his uncle, Ruslan. The New York Review of Books tracked him down and revealed him to be Mikhail Allakhverdov, a Rhode Island man who knew Tsarnaev, but claims to have nothing to do with his radicalization. “I wasn’t his teacher. If I had been his teacher, I would have made sure he never did anything like this,” he said. He added he is cooperating with the FBI investigation and has been told his case is about to be closed.
