0 these are not static situations. you must always look at different options based on the reality on the ground and based on what you want to achieve, based on the future and international intelligence. >> heather: u.s. intelligence shows that syrians may have used nerve gas against its own people. >> we want to make sure we look before we leap. what we're doing is actually helpful as opposed to making it more deadly or more complex. >> heather: so, there are also concerns that u.s. weapons could end up in the hands of al-qaeda linked groups helping the syrian opposition. >> gregg: fox news confirming five troops are dead in afghanistan. the state department was part of the international coalition were killed in a roadside bombing in southern afghanistan. we are learning that an afghan army soldier turned his weapon against coalition troops killing two international service members in a so-called insider attack. >> heather: developments in the boston bombing investigation. a search of computers in tamerlan tsarnaev's home turned up an online al-qaeda magazine. that publication is called inspire and it's known for sharing instruction on how to make a bomb. sources say cath russell's, wife of the dead bombing suspect, actually communicated with her husband after the attack during the search for him as and his brother. more problems for the family, fiend go a place to bury tamerlan tsarnaev. david lee miller has the latest. >> reporter: at this hour the body of tamerlan tsarnaev is at a funeral home in worcester, the head. the death certificate that tamerlan tsarnaev was shot by police and then run over by a motor vehicle. heather, one other obstacle impeding a quick burial, the family says it wants its own independent autopsy and so far that has yet to take place. >> heather: run over by a vehicle believed to have been driven by his brother. david lee miller, thank you. >> gregg: a lot of people want to know what tamerlan tsarnaev's wife knew about it, if anything at all and when she knew about it. investigators believed that weapons were built inside the home she shared with the bombing suspect. joining us mary ellen o'toole, former f.b.i. profiler. good to see you. if these bombs were not made in tamerlan's cramped apartment he shared with his wife, could she possibly have simply turned a blind eye to it, rationalized it? or might she be implicated as a co-conspirator? >> it could be either one of those or somewhere in between. when you have a small area like that, it's absolutely logical that she would have seen something, heard something, smelled something. whether she looked at it as you say, she rationalized it or explain it away, that is possible. to say that she was completely oblivious to it, in my experience where husbands and wives live in a small area, the husband is involved in serious criminal activity, it's not likely the wife was completely unaware of what was going on. >> gregg: what if she was absolutely controlled by him? >> i think that is very good possibility. investigators are going to be looking at that. controlling is a process that takes a period of time. it's not just the overbearing and demeaning, but it's the process by which the husband would have isolated her, separated her from family and friends. had her engaged in demeaning behavior, embarrassing behavior. it would have taken time for her to get to the point where she would have been what we call a compliant individual. >> gregg: i'm not sure knowledge would be enough that would have to be intent and conspiracy, the law requires an overt act and further answer of the conspiracy. but dzhokar tsarnaev reportedly told the f.b.i. they learned how to make the bombs through an online magazine called inspire and that has been found on katherine russell's computer along with other jihadist material. it's still another obstacle to prove that she is the one who accessed or downloaded it. it may have been her computer but it may have been somebody else that used it? >> that's right. it could have been a computer that everyone at the home used. they are definitely going to have to take a look at it. investigators will take each little piece and those pieces together will add up to just exactly how much did she know. i think this is extremely important. when you have a really controlling, demeaning individual, they may want you as the wife or the brother to know something, but they don't want you to know everything. so investigators will also be considering that, that he very likely withheld information that only he knew. >> gregg: the other question, did katherine help her his hide from authorities when she learned that her husband may be responsible. here the law in massachusetts. on accessory after the fact. you have to prove the defendant after the commission of a felony harbors or con seats or maintains and assisted principal felon which would be tamerlan or his brother, knowing that he was an accessory with intent to escape detection. those are three very difficult legal hurdles to overcome? >> they are absolutely very difficult, but the issue is going to be, if charges are filed against her, even if there is a just a minimal amount of information, this is such an egregious case, an attorney is going to say do i have enough to charge her. they are being careful that they don't make a deal with the devil. by that i mean, how much does she know before they can make a deal with her. >> one last question, officials say that russell called her husband when she saw his photo on television but did not notify authorities which raises questions. is there anyway that they can recover that conversation? i read one counter terrorism expert. some conversations are recorded and can be recovered? >> i think as the conversation that can be recovered based on the type of phone she used in and the current technology. they will do absolutely everything they can to recover that conversation. they will do use every resource possible. they want to know what was spoken between the two of them. >> gregg: mary ellen o'toole, thanks for being with us. >> heather: still to come, thousands of homes are threatened right now at this moment as wildfires rage across southern california. we are live on the ground for the latest as firefighters try to beat back the flames. >> gregg: and nra holding annual convention this weekend. >> so for those of you in the media who are here that don't understand what we are and what we believe. i'll be crystal clear. we are the moms and dads and sons and daughters of the nra and we want to prevent newtown and not take advantage of that. >> defending the second amendment as it kicks off a convention in the national discussion on gun rights. >> heather: and argo, a hollywood thriller, now here is the real sting. national geographic the american diplomats that were rescued during the iran hostage crisis. two of them are with us to share their amazing story. i'm thinking this is it. they are going to break-in and we have no defense.
