match it to something to make any sense out of it. so they re obviously clearly looking at the wife? they have to be. she lived in that apartment. but when you talk about dna on a bomb is there a way for them to know for example whether the dna on the bomb frag camement came from a possible victor is it somewhere so embedded in the dna of the bomb for lack of a better word, that you would be able to say this dna was likely from someone around the building process as opposed to a victim? no erin. you raise a good point. dna could be from one of the victims. it most likely would have been in the form of blood rather than skin cells. but, again, we re talking about a comparative science. and we re talking about the source of that dna on the bomb. you need to compare it with something. you need to have some other profile to make the comparison. and that s why katherine russell is an obvious choice. it certainly is possible that it came from one of the victims as
exports. they re not going to do anything that gets in the way of that. in november when we told you about a factory fire in bangladesh that killed 112 workers, we said it was time for stronger unions to protect the rights of the workers. we needed that in the beginning in the united states, too. now with another 400 dead it is more important than ever. will it finally be the time? thank you so much as always for watching. see you back here tomorrow night. ac 360 starts right now. good evening, everyone. nba hall of famer charles barkley, kenny smith and omeka okeafor join us for a history-making night in pro sports. pro center jason collins becoming a true pioneer, the first big league male athlete to say he s gay. also tonight, breaking news. female dna found on the boston bomb parts. female dna, as the fbi takes dna samples from the home of the dead suspect s widow. we begin with that ground-breaking day in u.s.
well. we have to interpret what we see. as the dna they re checking her dna. if it ends up being that it is her dna, how do they make a link that she then knew about it and what its purposes were as opposed to for example, touching a pressure cooker that her husband took out of the box and left on the kitchen counter? erin you raise an absolutely perfect question there. all we can say is that her dna is associated with the bomb or a part of the bomb. how it got there, when it got there, could it have gotten there simply? of course. it certainly gives us more leads and the focus of the investigation would then be on her if in fact it was a match. lawrence, thank you very much. we appreciate your taking the time as we have reported investigators with a lot of questions about several people one of whom is tamerlan tsarnaev s widow, who lived in that small apartment and in very close quarters with her husband in the months leading up to the bomb and in the days after the
chechnya one disturbing trend, in that part they actually have a for them there. they re called black widows named that way because some are wives of insurgents killed by government forces who themselves then take up the cause and become suicide bombers. nic robertson is in dagestan with an outfront investigation. reporter: in dagestan s capital last may, an inferno. moments earlier, a female suicide bomber known here as a black widow detonated a bomb at a police checkpoint. minutes later, another blast. the following day reveals the full horror. the black widow s brother, driving a car bomb blew this fire truck apart. callous timing killing the emergency service workers just as they arrived to put out the flames. a brutal conflict spilling over from neighboring chechnya playing out as tamerlan tsarnaev
blood dna could have indicated that this came from a victim. skin cell dna, as joe ind indicated, from someone along the manufacturering line or someone involved in the making of the bomb. a possible link between tamer tamerlan tsarnaev, the older brother, and a jihadist in russia who died in a firefight with police while tamerlan tsarnaev was in the region right? that s right. what we re learning is that they re looking into the possible link between tamerlan tsarnaev and a young boxer, canadian turned jihadi. he and six others killed in the dagest dagestan region in july 2012, exactly the same time that tamerlan tsarnaev was in the very same region. his body was prepared for burial by an imam july 14th. they believe it was brought down from the mountains and prepare days later, tamerlan left
