CNN, now, has just confirmed its information about the Boston bombing. The authortity is now making a direct connection, between the dead Boston Marathon bombing suspect Tamerlan Tsarnaev, and the triple homicide back in 2011 that left a close friend of his dead. We talked about that back when the bombing occured.

It comes after an acquaintance of Tamerlan Tsarnaev reportedly confess to taking a part in those killgs, before authority say he attacked and was shot dead by a FBI agent who was interviewing him.

Susan Candiotti has been working her source. Shejoins us now. So, Susan what's the lastest on this?

--Hi, Anderson. Tamerlan Tsarnaev is now linked to those vicious triple murders outside Boston in 2011. That's what's been confirmed was by a federal law enforcement official. The link allegedly coming from a man who's been questioned today by the FBI, and Massachusetts State's Police.

Now, that man's name is Ibragim Todashev. A law enforcenment official tells me he fingered Tamerlan Tsarnaev in the triple murders, described to me as drug-related. We have mug shots of Todashev from two unrelated road rage cases in both Orlando and Boston. Todashev was fataly shot in his home in Orlando during a confrontation with the FBI, right after he confessed to the triple murders.

Sources tell me it was self-defence. A law enforcement source tell my colleague, Deb Feyerick, the man attacked the agent with a knife. And the FBI teams in Orlando reviewing what happened. And Anderson that's standard operating procedure in any FBI shooting.

--So do have any idea with the motive was for the triple murders it was drug related?

--Yeah, my source tells me it involved some kind of drup rip-off. And the Tamerlan Tsarnaev's friend didn't want risk getting caught, so they killed him.

--Is any connection between the dead man in Orlando and the Boston bombing?

--Well, be serious, Anderson, the FBI hasn't found a link so far. But agents first became interested in this man because my source tells me they came up with leads that Tamerlan and his younger brother Dzhokhar knew the Chechen in Orlando. And the Chechen, and he was granted political asylum here in 2008, used to live in Boston just like Tsarnaev did. Agents will check in out anyone who know the Tsanaev brothers. Now, our CNN's affiliate WCVB says the FBI looked at this apartment near Boston, where Today she lived, shortly after the marathon bombing. And they also came up with other relating including cellphone connections between Tamerlan and dead man in Orlando. Our Banfield also reporting on the Massachusetts State's Police been getting involved.

--Is the FBI looking into the man in Orlando and Tamerlan Tsarnaev's friend for radicalization links?

--Yeah, we do know that all 3 men had checked out a Marshall Arts Website and online forum, and so had Russian-Canadian boxer turned jihadist William Plotnikov.

You remember that I told you about him before, the FBI's been investigating links between him and Tamerlan. Because Tamerlan was in Russia last year, and came home to Boston right after Plotnikov was killed by Russian forces. And the FBI has been checking to see whether Tamerlan met with him while he was there in Russia.
