you need hands-on practice for a very long time, especially when you re making these things go off under pressure like a gun fight, or you re placing bombs. you just can t count on people you ve actually made these devices? yes. reporter: well, basically what i can tell you, anderson, is that tsarnaev is in stable condition and doctors at beth israel as well as u.s. marshals decided he was stable enough to be able to be moved to this facility. happened early this morning, we re told just around 5:00 a.m., and immediately upon tsarnaev s arrival, he was put through something that s called the intake screening program. that s a step by step program. first step on that is he goes through a strip search. after that, he has a medical screening. then a psychological screening.
are not involved in the investigation but from the outside with experience, that s what they re saying. nick, you ve been now in dagestan in russia for awhile, tracking down this story. it s possible we may never know the specifics of what that elder brother was doing over there six months or who he met with, when he was back in russia last year, correct? reporter: absolutely. there are still people trying to piece it together. my conversations with russian security services, they give no comment at all but there s a suggestion perhaps there is more information ticking around on their side of the fence. we do know this extremist militant was attending the same mosque here, an islamist accused of extremism by authorities. we know they attended the same mosque because his mother told me so. the question here is whether the men actually ever met at all or whether there was some other kind of link, perhaps tamerlan tsarnaev had to militancy here. he was here for six months. we don t kn
