but the questions are what did he do, where did he go, whom did he meet. what we do know is when he returned to the u.s., he opened a youtube account, posting increasingly militant islamist videos, including one from this man, abu dujana, a self-styled jihadist leader from dagestan. and he is associated with this man, duku umeroff. this man has been dubbed the osama bin laden of chechnya. he as vowed to attack not just russia, but the u.s. importantly, his group has denied any responsibility for boston marathon bombings. it s not known whether tamerlan ever met with dujana or umeroff. as the investigation continues, a number of open questions have been raised. could tamerlan have met either of these men? did he learn gun handing or bomb-making from them or any of their foot soldiers? until now, there has been no
contact with jihadists when he visited russia in 2012. after returning to the u.s., a video known as abu dujana was posted and then removed fr. there s something we re missing. i have an uneasy feeling about it. not having the facts i can t assure you 100%. reporter: tsarnaev s brother claims they had no contact with any foreign terrorist organization. and online preachings of anwar al awlaki are likely influences but it proves elusive, there is no doubt in his ability to conceal the sinister plans from those closest to i am hahim, hi parents and even his wife. this came as an absolute shock to them all.

nick paton walsh joins us now from dagestan to explain what is in this youtube clip. absolutely. shortly after his return from russia to the united states, tamerlan tsarnaev posted on his youtube channel a link to a video of an extremist who was killed not far from where i m standing by russian special forces. just last december. is there a connection between this gun fight involving militant and police in dagestan, and one of the boston bombers? the you if tube page of deceased brother tamerlan tsarnaev suggests there might be. he put up a link to a video titled abu dujana. the video was removed but cnn has now found it, and it shows this man. abu dujana is the name used by an islamist militant.
