As officials continue to investigate Boston bombing suspect Tamerlan Tsarnaev's 2011 trip to Russia, a growing list of his contacts there is heightening suspicion that he may have adopted his radical views during his time there. Tsarnaev's voyage to Russia was allegedly a vacation to visit his uncle, a major player in Russia's Islamic world who is now being held by the police. Authorities suspect it was his uncle who brought him to a fundamentalist Salafi mosque in Makhachkala, where he may have been approached by a variety of contacts about joining Russia's Islamic insurgency. Russian authorities continue to assert that Tamerlan was radicalized in the United States—while his family insists that his trip Russia trip was spent "reading novels and reconnecting with his family."
