0 and according to what we have been sold by several officials, the fbi had been talking to him for the last several days and he was confessing to his role in a 20 11 triple homicide in the same community where the two men were living. in which three people had their throats cut. they had marijuana sprinkled over them and cash. no one had ever been arrested in that. and according to officials, todashev became violent, lunged at the fbi agent at the knife and at that point he was shot. it is not clear at this point who fired the shot. because we've been told by law enforcement officials that the fbi was there in this house, in orlando. also massachusetts state police and at least one orlando policeman. so the question of who shot him is still under investigation. but the shot was fatal, tamron. >> pete, are officials giving more information? of his and do we know what they mean by a role played in that triple murder? ? >> no. both tamerlan tsarnaev and ibragim todashev knew one of the victims in that homicide. that is one reason why i think authorities had initially wondered about whether the tsarnaevs had any connection to that. all they are saying now is that it is still under investigation. >> pete, thank you. greatly appreciate you making time for us. now to nbc in orlando, kerry sanders, what have you learn bed this individual? >> well, he was somewhat known just because the area where i'm standing, he would walk around this lake here and apparently had had some sort of problem with his leg and so that's made him stand out. plus, he spoke with an accent. we can look over into the area here where you see a tent set up in the background. that's where the authorities have been working under a cover there. the residents in this area say for the latest from orlando. we are breaking another story. another scandal involving the west point. now there is a bizarre turn of events at west point. >> this army sergeant first class, michael mcclendon wab who was a staff adviser at military academy at west point, has, in fact, been accused of placing hidden cameras and secretly filming female cadets in bathroom, showers and locker room facilities there at west point. he was relieved as doubties as staff adviser, sent up to for the drum in upstate new york where he has been charged of four counts, including an indescent acts and dereliction of duty. what makes this case a little odd of the recent cases, he had actually been a highly decorated combat veteran from iraq. earned a bronze star in baghdad where he worked on eod. that's those explosive ordinance personnel. he was a combat engineer. and they were in charge of going out and finding ieds and saving lives. now, interestingly enough, there, at west point, he was charged with looking after the well-being and discipline of 125 cadets. that was his staff advisory job. and now he faces these four counts of actually secretly tape recording female cadets in some pretty compromising positions. >> nick, thank you very much. in a contentious house hearing on the irs hearing now in its fifth hour. in fact, we have live pictures of the hearing happening on capitol hill. embattled irs official lois lerner envoccing her fifth amendment right not to testify. >> i will not answer any questions or testify about the subject matter of this committee's meeting. >> we will take your refusal as a refusal to testify. the witness and counsel are dismissed. >> lerner is the one, who two weeks ago, disclosed that agency targeted groups. she issued an apology before taking the fifth. lerner read a statement. >> i have not done anything wrong. i have not broken any laws. i have not violated any irs rules or regulations. and i have not provided false information to this or any other congressional committee. >> now that statement set off republican congressman of south carolina. take a listen. >> she waived her right to fifth amendment privilege by issuing an opening statement. she ought to stand here and answer our questions. >> is it possible that we could narrow the scope of questions and that there are some areas that you would be able to answer any questions on here today? would you be willing to answer questions specifically related to the earlier statements made under oath before this committee? >> i decline to answer that question for the reasons i've already given. >> for this reason, i have no choice but to excuse the witness, subject to recall -- >> with that, lerner and her attorneys got up and left the hearing. joining me live from capitol hill, nbc news, luke russert. luke, that's what a lot of folks are noticing. same issue that congressman goudy pointed out, that lerner would read a statement saying there is no wrongdoing but then envoc the fifth amendment. >> yes. she pretty much defended herself saying there is no wrongdoing but would not subject herself to exactly what her role was in this scandal that engulfed the irs. tamron, what is fascinating from watching today's hearing, last week was more political, trying to tie president obama to the irs and conservative groups. today the oversight committee, they really went into the sort of lack of institutional control at the irs and the systemic problems within the organization by not -- where they would not inform congress of these types of investigations. that they had done internally in the political targeting. take a listen to some democrats go after irs folks this hearing. >> you misled congress. make no question about it. you told us one thing when you learned, when you learned that our suspicions were true, when you learned that there was a list, you did nothing. you did nothing. you be a docated your responsibility. >> do you take responsibility for what happened in the cincinnati office? >> do i take responsibility for the list? >> yes. >> being done? i don't take personal responsibility for there being a list with criteria put on it. but i do accept the fact that this did happen on my watch. >> so tamron, what you saw there, essentially was democrats going into the irs officials and saying, why was there so much disinformation, misinformation, rather, coming out of the irs when they were specifically asked about this type of targeting. it was fascinating hearing that touched on that and it brought up this whole idea of who was in charge at irs. how come the inspengtor general -- the inspector general was asked, why weren't they operating more quickly in terms of responding to congress. which you saw more than anything was the oversight committee very upset that congress, the legislative branch role, of oversight here, was not being catered to in a prop are way, tamron. >> luke, how much is said that lerner perhaps decided not to answer the questions due to the fact that there could be a criminal investigation here? >> that certainly is something that had been mentioned today. there is, even a request for republicans, to have a special prosecutor look into ms. lerner and what happened at the irs. certainly the fact of the matter she thought it was okay to give a statement but would not give herself to questioning, lead to think, maybe there is more there and to scrub away at. it will be interesting to see what plays out. but lois lerner is someone that both democrats and republicans both feel she should lose her job. this just feeds more of that. >> luke russert. thank you. >> take care. >> president obama will in fact travel to oklahoma this sunday to see the damage for himself. homeland security secretary janet napolitano already on the ground as we get early estimate as to the cost of the disaster. we are also learning, the most important details. we are learning about those, the youngest victims, who lost their lives. in fact, the father of one little girl has spoken out, talking about his daughter. we will play what he said. and a jury deciding whether jodi arias lives or dies for killing her ex boyfriend. >> a lot of people out there feel like the only true justice for travis alexander is for you to get the death penalty. >> that's not justice, that's revenge. >> you can find more information at tamron hall@"news nation."
