ORLANDO, Fla./WASHINGTON (Reuters) - A special Federal Bureau of Investigation team from Washington on Thursday began reviewing the death of a Chechen immigrant linked to the Boston Marathon bombing suspects, a day after he was shot and killed by an agent during questioning in Orlando. The dead man, Ibragim Todashev, 27, was a friend of suspected bomber Tamerlan Tsarnaev and was under investigation for alleged ties to a triple homicide in Massachusetts in 2011, according to media reports citing law enforcement officials. The FBI has made no official comment about the shooting since a brief statement on Wednesday morning when it said Todashev was killed after he suddenly attacked an agent during an interrogation at his Orlando condominium.
