pamela brown is in texas at ft. hood. barbara starr is over at the pentagon.hat did you just learn about the suspect and the events leading up to the shooting? >> wolf, we have some clarity now on new details. you'll recall that the army says that ivan lopez reported a traumatic brain injury at some point, but it had never been clear what they were talking about because when he served in iraq he had no contact with enemy forces there. u.s. official, military official familiar with his record says what happened was while he was in iraq he suffered a fall while on patrol and reported hitting his head. that was the traumatic brain injury that he reported that u.s. military officials had been looking into on patrol in iraq. he fell and hit his head. another issue has been that the claim perhaps is he did not get sufficient leave for his mother's funeral when she died. this u.s. military official says he was offered full bereavement leave but declined it and only took a few days at his own choice because he wanted to get to a course he was about to take in truck dr

our justice correspondent pamela brown is in fort hood. pamela, what is the latest tonight on what you're hearing? >> reporter: well, a u.s. military official with direct knowledge of the investigation telling our barbara starr that that traumatic brain injury that lopez had reported actually came from a reported fall during patrol, not from a traumatic event related to combat. and john, we learned from military officials today that there was an argument that escalated between lopez and another soldier in the moments right before this shooting. officials believe that was the impetus. and according to a father of one of the victims, it all started over a leave request form. cnn has learned in the weeks before his deadly rampage at fort hood, army specialist ivan lopez was creating a stockpile of ammunition. sources say when lopez bought his .45 caliber semiautomatic handgun at this store, guns galore in killeen, texas on march 1st, he also purchased what one source calls a large amount of ammo. cnn has also learned the 34-year-old returned t

we'll explore that possibility with pamela brown.t the same time, investigators on australian's "ocean shield" search are waiting to find out if a sample taken from an oil slick downwind of the search area is a match for flight 370. all of this while sonar technology on loan from the u.s. navy has finally been deployed to scour the sea floor. our rene marsh has all of the latest. >> reporter: a strategy shift in the search for flight 370's black boxes. >> it's time to go under water. >> reporter: and possible new evidence. >> an oil slick in the search vicinity. we'll investigate those to the conclusion. >> reporter: it's been six days since the last pings were detected in the south indian ocean. searchers believe the pinger batteries are probably dead. so they've retired the pinger locator and launched bluefin-21. the underwater vehicle will skin the sea floor for wreckage. >> i'll caution you to not raise hopes that the deployment of the autonomous underwater vehicle will detect aircraft wreckage. it may not. >> reporter: bluefin i

if this report is accurate and, again, based on pamela brown's u.s. with information they got from malaysian law enforcement sources, the co-pilot's cell phone did make contact with the krocell tower malaysia. >> that's a good question. there's a lot of different thought on that. let's show you one example at least from the simulator's perspective. we're flying over pyongyang dropping from 10,000 down to 5,000 feet. begins with a steep turn, a bank angle and then also into a strong descent. we're thinking, of course, initially when this aircraft went off course it was 30,000 feet over the south china sea and it was night not daylight and you couldn't see the maneuvering as well. it stems fit the story that taxpayer craft of course turned back, went over the northern part of malaysian peninsula and was descending at some point and when it got along pyongyang maybe could it have been around 5,000 feet, 4,500 feet and it was at that point that perhaps this connection was made. you know, there have been reports that you need to be at 3,000 feet, others sa

let's go to our justice correspondent pamela brown. she's joining us from ft. hood, texas. what are you learning over there, pamela? >> well, wolf, we're learning that investigators are right now in this moment looking at lopez's laptops, his cell phones, interviewing witnesses, trying to figure out and piece together why he did this, why he opened fire on his fellow soldiers. we can tell you according to sources and from general milley who spoke here earlier today, the general of ft. hood, that they're looking into a verbal altercation that possibly happened between lopez and another soldier. they're looking into whether that might have set him off. also they're looking into a leave request thats wa possibly canceled recently, whether that might have played a role. when general milley made clear here today was that lopez had a long history of mental instability. he says that was a fundamental underlying cause. he says there's an investigation under way to see if lopez is receiving the proper care, the treatment that he needed. and an overall investigation into the system as

in the meantime let's bring in our justice correspondent, pamela brown. information. what are you learning, pamela? >> reporter: we're learning from sources, wolf, that the shooter in this case used a semiautomatic handgun. again learning from sources it's believed that the shooter used a semiautomatic handgun. we know that atf agents are there on the scene right now. they're going to be look at where this handgun was purchased, how the shooter obtained it and so forth. so in this early stage in this investigation, it is believed again that the shooter used a semiautomatic handgun. and also we're learning from sources as we've been sailiying it's believed this was a soldier on soldier incident, that's how this started. sources are telling us the attacker here was wearing fatigues. so perhaps that's what is leading investigators to believe that this began as a soldier on soldier incident. but again it's still very preliminary. as we've been reporting, agents, fbi agents as well as local and state law enforcement there on the scene, still clearing out build

let's bring in cnn correspondent pamela brown. are investigators getting concerned? i think they are a little discouraged because the area offering the best hope for finding flight 370 isn't turning up any wreckage so far and they are almost done searching this targeted zone so it's forcing investigators to reconsider their approach. the bluefin-21 back under water today for its ninth mission. the air that the investigators are pinning their best hopes on is almost searched with less than six left to go. pings possibly from the black boxes were detected near there, as well as a final satellite handshake with the plane. if nothing is done soon, the australians will investigate and make the calculations and searching the right area. >> you may consider bring in other underwater search equipment. >> that's because in the next few days this targeted area is expected to be completely covered by the bluefin. last week, investigators announced the surface search would be over by now but despite a tropical cyclone north of the search area and still no sign of debris, it cont

pamela brown joins right now.are you hearing about the co-pilot's cell phone being on during the flight? >> we are learning from sources with knowledge of the investigation that the first officer's phone was not turned off like it should have been and was on 30 minutes after the plane communications shut off. this is according to information that malaysian shared with u.s. investigators a while ago. and that data is from a cell tower from penang, malaysia 250 miles from where that plane turned around indicating it detected a signal from the first officer's phone. >> there is no confirmation of calls that were made. >> that's right. officials have been pouring over phone records. and there is no indication that anyone placed a phone call on that plane. the transport minister in malaysia wouldn't rule out the possibility that he tried to make a call and that is a possibility. we just don't know. >> does it raise suspicions even more about what was going on in the cockpit? how are investigators looking at it? >> it a

pamela brown. along with former oceanographer, van gerley.at does it say to you, it went from 35,000, normal cruising up to 39,000 feet after it made that surprising left turn after transponders stopped working. spent 15s in vietnamese airspace and eventually flew over the malaysian peninsula. >> i think it confirms it was under human control. somebody was directing and flying that plane. now, do we know why? we don't know. but it was under human control. i think, you know, the more we get information about this and confirm it, the better understanding we have of the flight path and what might have been happenening. >> that 39,000 is near the maximum. could go up to 41,000. that's about it. pamela, how did this play into your reporting over the path few days that the co-pilot had his cell phone on trying to establish a signal with the cell tower. >> we know as you point out, there was some sort of -- i should actually rewind a little bit. this information has been shared with u.s. investigators, data that the co-pilots -- data from it was det

let's go live to our cnn justice correspondent pamela brown. she's at ft. t. pamela? >> reporter: wolf, military officials confirming today there was an argument that escalated between lopez and another soldier in the moments right before the shooting happened. officials believe that was the impetus that caused lopez to snap and we're learning more that it started over a leave request form. cnn has learned in the weeks before his deadly rampage at ft. hood, army specialist ivan lopez was creating a stockpile of ammunition. sources say when lopez bought his .45 caliber semiautomatic handgun at guns galore on march 1st, he also purchased what one source calls a large amount of ammunition. the 34-year-old returned to the store repeatedly to buy even more bullets. it's the same place where major nidal hasan bought the weapon that he used in the 2009 ft. hood attack. in a press alert today, they believe the shooting started after a dispute with a soldier. >> we believe the precipitating fact for was an argument in his unit area. >> reporter: he picked up a form o

let's begin our coverage this hour with our justice correspondent pamela brown. pamela?, we could see a shift in search efforts very soon. crews are wrapping up searching the most promising area of where the plane is thought to have gone done. and with no trace of flight 370 so far, the question looms, what direction will investigators go next? today, potentially the final day of searching the part of the ocean investigators thought was their best hope. >> place they had to look because they had the pings, they had the inmarsat data, had the fuel consumption of the aircraft. >> reporter: crews so far covered 90% of a 6 mile radius area with the bluefin looking for the missing malaysian plane with no luck. nearly three weeks ago the towed pinger locator detected signals in close proximity thought to be from the plane's black boxes. crews said the second ping was the highest quality and they launched the bluefin in this small area first. during its day-long missions, the bluefin has been pushed to its limits diving deeper than designed and uses side scan sonar then resurfa

let's go to pamela brown who is working the story for us today from washington. if the blue fin, you know, finally searches the entire, 100% of the area with nothing to show for it, what next? >> you're right, brooke. it's already searched about 95% of that area. we're learning new details about what the next phase of the search will look like as the blue fin wraps up scouring the targeted area. a decision has been made to expand its search to areas adjacent to the first radius. we know the ping to the north is seen as a promising area. ing a australian officials are not commenting on right now but officials have said they are hammering out a long term game plan. the only submarine involved in the search efforts is being pulled out by the naval officials since there is no longer any prospect of detecting pings it no longer makes sense to use those capabilities. >> okay. pamela brown for us in washington, thank you so much. let's bring in our panel here. joining me now, mary sceavo at the u.s. department of transportation. welcome to both of you. talking with the

our justice correspondent, pamela brown. pamela? >> for the first time malaysian thundershowers are on the record confirming what cnn has been reporting, that this is, in fact, a criminal investigation and has been for weeks. overnight we learned that malaysia airlines sent out an alert to its employees heightening cockpit security, perhaps another indication of where this investigation is focusing. malaysian officials made a bold statement overnight clearing all the passengers of any role in taking down the train, ruling out hijacking, sabotage, personal problems, and psychological issues. >> this is a criminal investigation. it is ongoing, and we are still waiting for expertise from experts overseas and internally. >> the malaysian investigators say they haven't finished interviews with all passpasseng relatives. how can they be so sure that the passengers on board from 14 different countries played no role? >> to say that everybody's been cleared is really an outrageous statement in my mind. this takes many months to do a thoroug

. >> cnn's justice correspondent pamela brown is live there just outside that entrance way on to the fort hood. pamela, i know officials searched shooter's home. what did they find? >> reporter: that's right, brooke. i spoke to a law enforcement source earlier today and learned that they didn't find any physical evidence such as a suicide note that would indicate a motive. now we know from sources that the fbi and army investigators have been searching his computer and interviewing witnesses trying to figure out what triggered the shooting on wednesday. and looking at several possibilities. one is whether he was angry over recently -- a recently canceled leave. we heard from the general of fort hood yesterday, talking about a verbal altercation between lopez and another soldier right before the shooting happened. and also, brooke, the general talked about his long history of mental instability being a fundamental underlying cause. we learned he suffered from depression, anxiety, a sleep disorder and was taking several medications and being treated for those issues. and, of course, the

let's get the latest from our justice correspondent pamela brown. >> the area offering the best hopeckage so far. that forcing investigators to reconsider their approach. the bluefin-21 back under water today for its ninth mission. the area investigators are pinning their best hopes on is almost searched with less than a third still to go. it's a roughly six-mile radius search zone considered the most promising because pings possibly from the black boxes were detected near there as well as a final satellite handshake with the plane. if nothing is found soon, the australians said they'll re-evaluate if they're using the right tools, made the right calculations and are searching the right area. >> consider bringing in other underwater search equipment. if nothing is found in the next few days. >> reporter: that's because in the next few days, this targeted area is expected to be completely covered by the bluefin. last week, investigators announced the surface search would be over by now. despite a tropical cyclone like a hurricane north of the search area and no sign of debris, it cont

pamela brown is here. have officials announced what the next step will be?nounced what the next step will be or what it will look like. but we'll likely see a shift in the search efforts very soon. today, potentially the final day of searching a part of the ocean investigators thought was their best hope. >> it's a place they had to look. they had the pings and inmarsat data. everything pointed to this area. >> reporter: crews have covered 90% of a six-mile radius area of the bluefin looking for the missing malaysian plane with no luck. nearly three weeks ago, the towed pinger thought to be from the plane's black boxes and the second ping was the highest quality and that's why they launched the bluefin in this small area first. the bluefin is being pushed to its limits, diving deeper than it is designed, using side scan sonar and then resurfaces so data can be analyzed. it's something familiar to david gallo, who was part of the search for flight air france 447. >> it's a matter of sitting in a room with a white board and there was a long period, months befo

justice correspondent pamela brown is on the scene for us with new information. pamela? >> reporter: that's right, wolf. according to a source with firsthand knowledge of the investigation, we have learned that the suspect in this stabbing spree, a 16-year-old, male sophomore at the high school, has been charged as an adult with attempted homicide. we know that he appeared before magistrate earlier this morning during his arraignment, and he has been charged as an adult with attempted homicide. now, this all unfolded around 7:00 a.m., before classes started at franklin regional high school and we're told by authorities that a lot of students were at their lockers when all of a sudden the suspect, alleged attacker, wielding two kitchen knives, went through and started stabbing people at random. we've learned 19 of his classmates, as well as one adult, rushed to the hospital. at this hour, wolf, four are still in the icu, critical condition, two in good condition, five in fair condition. several have been discharged. but as you can imagine, there was just mass confusion an

let's bring in our justice correspondent pamela brown with the latest information. pamela? >> that's right. we're learning malaysian and australian officials are working together to come up with a long-term game plan if nothing turns occu s up in this targeteh area. the bluefin-21 is almost done searching here. the underwater six-mile radius zone considered the most likely area where the plane went down. >> if they were thinking, if you remember, this was the bulls eye, they were going to through the one dart into the bulls eye, i think it might be time to make the bulls eye bigger and expand that area. >> crews could finish searching in the next day. if nothing is found, investigators will regroup, but it's not necessarily back to square one. >> we only have a specific amount of data, a certain amount of data that's led us to this part of the world. i think we have to be encouraged by the fact we've been led to this very specific and small part of the indian ocean. >> the bluefin has only searched around the second ping, which was thought to be the most likely area. now of

hood, texas, where pamela brown is on the scene for us with the very latest. pamela? >> wolf, at this hour, we're learning that sources from the fbi and army investigators are being looking at lopez's cell phone and computer and interviewing witnesses. investigators are still trying to figure out the why, why did lopez open fire on his fellow soldiers? he talked about the fact that investigators are looking into a verbal altercation between lopez and another soldier and says that soldier's unstability played a role in what happened. cnn has learned that the handgun lopez used in wednesday's shooting was purchased here at guns galore, a few miles from the base on march 1st, shortly after he arrived in texas. sources tell cnn they do not believe that he was planning a shooting at the time. investigators don't know what set the 34-year-old off except that he was undergoing an oong tea and sleep disorder. he walked into a medical brigade base and began shooting. >> take shelter immediately. >> immediately the base goes on lockdown. >> we have an active shooter coming in.

. >>> inside the planes cockpit, all airliners, pamela brown is looking at this part of the story.hat are you finding out? >> wolf, cnn is learning that malaysian airlines has stepped up security following flight 370's disappearance. the airline will not tell us what that means. malaysian officials believe the disappearance of the flight was a criminal act by one of the pilots with someone else. this shows flight 370 pilot zaharie shah with a woman and he invited her and a friend inside. the airline was shocked by the photo but now what sources are saying to investigators is flight 370 turns off course as a criminal act, industry experts are asking if cockpits are really secure. >> this should be for every single airline around the world, this should be the wake-up call that says, let's review our procedures. >> reporter: after hijackers breached security on four planes on 9/11, cockpit doors were reinforced but even in a post 9/11 world, current regulations are not always strictly followed by every airline in every country. >> human nature seems to take over. there's some type of

just as pamela brown worked to pin it down but she did not stop there. >> the bottom line this is a tinyce of the puzzle and experts and sources are trying to figure out what this information about the co-pilot cell phone really means. what we do know here is that if any of the passenger phones were on and not in airplane mode they should have dinged that cell phone tower as well. and considering 30% of people forget to turn off their phones it's likely not just the co-pilot's phone. but the co-pilot's phone should have been off. so the question of course looms was it on from the beginning of the flight or turned on before it hit that cell tower? and i want to make it clear here, sources saying there is no indication any calls were placed and just because a phone connects with a cell tower doesn't mean that a call can go through and it is tough the get the answers and information we need to know exactly what all of this means. >> any information from the cell phones could aid the overall investigation. >> yeah, right. it could. if certain factors become clear like the phone was turned of

pamela brown, thank you so much. >>> i want to bring in dave soucie and rob mccallum. the royal navy just withdrew the submarine from the search. does this mean that investigators are giving up entirely? >> no. i think it's a distribution of assets. it indicates to me that they are taking a little bit of time to regroup, make sure they understand where they are with it and then move forward again. i don't see something that it's something that they are giving up. i don't see it as anything giving up at all. >> the tireless submarine is giving up and the "echo" is going back to port to restock and refuel. do you believe that there's a waning sense of urgency in this search? >> yes, i do. there's always a sense of urgency in the beginning of a search, first to look for survivors or try to capture any debris or in this case pinger signals. but once those chances are gone, then there needs to be a tempo shift, if you like, and it's about accuracy rather than speed. whatever is done from now on, we need to make sure that once an area is being searched it can be ruled out of

our justice corner pamela brown is here, working this part of the story. i know we reported on this a few days ago, but you're getting more information? >> yeah. you know, questions about the new information really are mounting, because there's so many more unknowns than known at this point. sources, experts are trying to figure out what it means, if the cell phone connected with that tower, was the phone on in the beginning of the flight or turned on mid flight? >> reporter: malaysian officials investigating flight 370's disappearance have told u.s. investigators they have data that shows first officers hamid's phone connected to his cell tower near malaysia once the plane was airborne, we don't know whether the phone connec d connectedconnecte with other towers. >> it's odd it would have connected with one cell tower. you might have thought if the phone were on for a longer period of time, that multiple cell tower would have picked it up. so it certainly is a little suspicious in terms of the information at this point. >> reporter: the plane would likely
