we'll find the airplane. >> thank you for staying with us. cnn's live coverage of flight 370 and the ft. hood shooting continues live from atlanta. this is cnn breaking news. >> hello and welcome to our viewers in the united states and around the world. >> a gunman opened fire at an american military base. >> we'll have complete coverage of that coming up. and live reports from texas and australia, next on cnn "newsroom." and big question after yet another shooting at the ft. hood military base in texas. >> officials say that ivan lopez

killed three people before committing suicide. >> and the commander said he served in iraq in 2011, and was being evaluated for post-traumatic stress disorder. >> and that's after army major hasan killed people a few years ago. president obama talked about this. >> the folks there have sacrificed so much for our freedom. many people have been through multiple tours in iraq and afghanistan. when they're at their home base,

they need to feel safe. >> hasan was convicted last year for the 2009 attack at ft. hood and sentenced to death. he was targeting soldiers about to be sent to afghanistan. he was shot in the back and is paralyzed from the waist down. >> ed lavandera is there. what are you hearing? >> well, it's just after midnight and federal investigators are here at ft. hood and into the community. we know that investigators are at the home of ivan lopez. and we've already learned a

great deal. officials had been in the process of treating and diagnosing him for ptsd. psychological issues as well as anxiety. and investigators and officials say they still do not have a motive for why he carried out this attack just after 4:00 p.m. in central texas. but they do describe the methodical nature of the attack. >> it is believed that we walked into one of the buildings, opened fire. got into a vehicle, opened fire again, and was engaged by local

law enforcement. >> reporter: he turned his gun on himself. we were at the apartment complex and spoke to a neighbor as news was breaking out. that ivan lopez's wife was standing around with others, trying to gather the news. that's when she first found out that it had been her husband. she had been worried about it, and then got the news. we're told that she's cooperating with investigators. various sources are telling us

that. a great deal of work and attention, concern for the victims that are still being treated. we understand that there are 16 people injured. some trying to escape, climbing over glass. but other people shot, sustained wounds in the attack. nine soldiers are in the hospital, three in critical condition. and so far, the death toll, three victims. the fourth victim was the shooter -- the fourth person that died was the shooter himself. but a great deal of attention being paid to the wounded victims. natalie? >> we wish them well. it's surreal that his wife was standing with others. what must have been going on in

people's minds? what was it like to hear that yet another shooting was under way at the base? >> reporter: i covered that shooting years ago, and also the trial of hasan. it took a great toll on this community. and this is an army installation where tens of thousands of soldiers have come through. this is something that there's been a lot of pain and anguish that this community has dealt with since 9/11 and the wars in iraq and afghanistan. it's chilling and very

difficult. but this is a community that has dealt with it before. it was eerie, everything was locked down when we pulled up. very quiet. and after that all-clear that was given after the shooting, and everything was brought under order, that everything got back to normal. you saw a line of cars getting off the installation tonight. a chilling scene, leaving many scratching their heads tonight for sure. >> and we'll learn more in the coming days. ed, thank you. john? >> well, so many questions about a motive. for answers on this, i spoke with russell honore, a retired general of the u.s. army.

everything we've heard from ft. hood indicates this was a troubled soldier dealing with mental health issues. >> that's the indication based on the reports. we'll know more in the hours to come. but as a soldier on the army team when something like this happens. occasionally, it's a crime of passion. but many of these incidents come back to significant mental issues. unfortunately, it does come to that. >> and when a weapon is brought on to that base, how does that happen, especially with what happened in 2009? >> well, there's an open carry law in texas.

you can't have individual weapons, carrying it around on the base. so, if you were caught carrying a weapon in your car, if someone were to see it, you would have to go before your commanding officer and probably be punished. so, we have strict rules about it. unfortunately, none of the rules prevent people with bad intent from bringing a handgun to ft. hood. -- that's a normal procedure. we'll pass any lessons on. but it's a case of, to get on

ft. hood, it's a sprawling insulation. with a community of over 90,000, that go in and out every single day. to get off ft. hood, you need to show i dentification. that's what happened -- it's happened twice in four years at ft. hood. >> and this is the biggest military installation in the united states. many of the soldiers have been in iraq and afghanistan. right now, they're under fire at home. how will they be dealing with

this in the coming hours and days? >> well, it's almost like a kick in the gut. our military posts are our saing tu wary. for our families, and when we come back, it's a place where you're not carrying a weapon 24 hours a day. it's meant to give you a sense of security where you can relax in a family environment. so, it breaks the trust we have with our soldiers and families that we live in a secure environment. and in each case when this

happens on an army post, it's a individual dealing with behav r behavioral issues. >> thank you, general. and talking about what happens on military bases around the united states. >> and a lot of questions. as the commander said, they'll be assessing what to do. after the break, the latest on the information from malaysia. and a live report on the search from perth, australia. you're watching cnn. stay with us. the check? [thinking] i'm still working. he's retired.

and welcome back. woor following breaking news of of ft. hood, texas, where a shooting has left four people dead, including the gunman. >> the base commander said that he had multiple issues. and has been identified as ivan lopez. >> and president obama says he's heart broken and insisted that

they will get to the bottom of what happened. >> and chuck hagel spoke from honolulu. >> when this happens, something isn't working. we'll identify it, get the facts and make it work. >> now for the latest details on the situation at ft. hood. the search for flight 370 has shifted once again. >> eliminating areas where nothing has been found. malaysia's top police official says that the mystery may never be solved. all of the passengers have been

cleared, and that there's nothing suspicious about the pilots. but nothing said about the rest of the crew. >> and the search in australia, and the quest for answers continuing. malaysia airlines is taking action. beefing up security. more on that from ka uala lumpu. >> reporter: as the search drags on, the malaysian police inspector general made one thing clear. >> this is an on going investigation. and still waiting for expertise reports from experts overseas and internally. >> reporter: so far, 170 people

have been interviewed, and cleared all of the passengers on board. now, back to looking at the crew to everyone working on the plane. >> everything. from beginning to the end. >> reporter: it's a painstaking process that so far has revealed very little. >> even the food. who prepared it? we have to look into that. >> reporter: in the meantime, sources confirm that malaysian airlines is increasing their security. no pilot or first officer will be alone in the pilot. as the days drag on, the families are more desperate for

answers. worried that time is running out as the batteries in the flight recorders come closer to fading. and news conferences reveal fewer details. can you tell us anything that you were able to share with the families? but the police inspector general is talking. and admitted something that officials have not said publicly until now. >> we don't know the reason. you see? we may not even know that. >> reporter: that's the last thing that families want to hear as they wait for answers to their questions. cnn, kuala lumpur. and a lot of people trying to answer the questions.

for the latest on the search, matthew chance joins us from perth, australia. >> reporter: about eight planes, nine ships engaged from various parts of the international community have started to search again. looking for debris from the missing flight that's not been found. no debris from the flight has been located in the past couple of hours. there was a joint press conference from the malaysian and australian prime ministers. they spoke about the thoughts

are with the families of the 239 people aboard, and will not give up. tony abbott stressing the international dimension of this. >> i do pay tribute to all the countries involved in the search. malays malaysia, china, japan, korea, the united states, the united kingdom, and new zealand. this is an extraordinary piece of international cooperation. >> in a time of great trouble, with loved ones missing, this cooperation has given us all heart. dink differences have been set aside

as 26 nations have united behind a common cause. >> in addition to the nine ships and surface vessels searching the seas in the indian ocean, there's also a british nuclear submarine searching as well. with very sensitive underwater detection equipment. looking for the pinger from the black boxes. they will run out just a few days from now. so, it's a race against time to find what may be left of the flight. >> thank you, matthew chance, live from perth. and a powerful aftershock in

chi chile. just one day after an 8.2 quake. >> that quake left six people dead. more than 2,500 homes damaged. for more, meteorologist -- joins us. >> one of 47 aftershocks -- this 7.6 has the potential for significant damage. the only one over land. the usgs estimating somewhere between one and ten fatalities. and six fatalities coming yesterday. so, the other one well offshore.

and the 8.2 -- 1.5 million quakes occur that you will feel. in the eight scale -- so a very significant event. felt by at least 167,000 people. and you would imagine this quake. happening about 17 minutes before midnight, a lot of people affe affected. and wave heights increasing to 2.4 feet. now, remember, yesterday's earthquake with a wave height of six feet. so, this is a significantly smaller event. being over land, the coastal

communities were affected. and aftershocks, two in the 6.0 magnitude. and well into the thousands talking about a magnitude 4.0. and something i talk about here, the plates in this part of the world, many of the biggest quakes are in alaska, chile, and sumatra. a lot of activity in recent weeks. >> and they're used to it, but don't like it in chile. >> and back in 2010, a quake left hundreds dead. a much better outcome than that one. and the latest on the deadly

shooting at the ft. hood military base in texas.

welcome back. 26 minutes past 1:00. a special edition of cnn "newsroom." >> and a shooter at an american

military base killing three people and then himself. >> he had served in iraq. had bhaifrl issues. and an all clear sounding about three hours ago. >> and let's go to tom foreman, giving us a closer look at the layout of the army complex. >> ft. hood is north of austin. in a wide area where it was established for tank combat operations. this is the main part of the base, running back and forth. the main gate here. it's a big base, but the bulk of

this incident happened right here. zoom past the gate to the hospital complex. this is where the commander says the shooting began, in the parking lots outside of the complex. from there, he says the gunman got back into his car, moving to the motor pool area. you can see some of the vehicles. and this road is called tank destroyer road. if you were to continue following the road, you would come here to where the incident involving major hasan occurred. and a fairly small area from start to finish with this tragic

event that has shaken this army post. you're watching cnn coverage of a deadly shooting at ft. hood. and this is not the first time this happened. more on that after this short break. coming back in two minutes. ♪ ...who work with regional experts... ♪ ...who work with portfolio management experts, that's when expertise happens. mfs. because there is no expertise without collaboration. mfs. we'll be here at lifelock doing our thing: you do your swipe from anywhere thing, watching out for your identity, daach or not. get lifelock protection and live life free.

this is cnn breaking news. >> once again, welcome to our viewers in the united states and around the world. >> thank you for being with us. >> and the breaking news, a deadly shooting in texas on an army base. >> three people were shot.

>> no indication it was a terrorist act, but nothing is being ruled out at least right now. >> ivan lopez was being treated for ptsd. >> military police officers responded. he was approaching her at about 20 feet. put his hands up. then reached under his jacket. pulled out the 9 mill. she pulled out her weapon, and engaged. he put the weapon to his head, and died of a self-inflicted gunshot wound. >> and reminding people of the

2009 shooting at ft. hood by nidal hasan. >> u.s. president barack obama says that investigators will get to the bottom of what happened. he spoke with memories of the 2009 shooting fresh in his mind. >> any shooting is troubling. obviously, this reopens the hurt of four years ago. we know the sacrifices that these families make. our thoughts and prayers are with the entire community. and we're going to make sure that the community has what it needs to deal with the current situation and any potential

aftermath. >> paula, thank you for joining us. he was being treated for depression as well as anxiety. what does that say to you about what his state of mind may have been? >> well, that says there was a lot of vulnerability here. i listened to the commander's press conference. depression and anxiety, they're a bit different. depression, feelings of sadness and hopelessness. it's a big key in this. we talk about him shooting others, but this is really a

suicide in many ways. anxiety is really about worrying. but the ptsd diagnosis is important. that's hyperreactivity. that would give me a lot of information to explain this behavior. >> and he was in the process of being evaluated if he was suffering from post-traumatic stress. that seems like an awfully long time, doesn't it? >> well, a lot of times with ptsd, you can have a delayed onset. and a lot of times, it's six months to a year before you can be diagnosed.

and in the military, a lot of times the process to diagnose it is a lot more deliberate. >> and one thing we should point out here, making the connection, we should be careful making the link between mental illness and the shooting. >> that's a great point. most people with ptsd and depression, they're not going to be violent. a key point. >> and looking at a motive, trying to figure out what happened here, when a shooter takes his own life, no suicide note left behind, how difficult is it to find out what happened with this guy? >> well, it will be interesting for them to look at the treatment notes.

sometimes, people do have a plan. they may not, but it's difficult. ultimately, you really, no matter your profession, you can't read people's thoughts. n >> a lot of painful days to come. thanks for joining us, paula. >> this is always sad, when they start painting a picture of who this guy was, and what was the problem at the end of the day. well, still to come, how can flight 370 disappear without a trace? >> but there may be ways to monitor every second of a

flight, even if it goes off radar. that's next. (clears throat) hi mister tompkins. todd? you're fired. well, gotta run. geico. fifteen minutes could save you fifteen percent or more. (agent) i understand. (dad) we've never sold a house before. (agent) i'll walk you guys through every step. (dad) so if we sell, do you think we can swing it? (agent) i have the numbers right here and based on the comps that i've found, the timing is perfect. ...there's a lot of buyers for a house like yours. (dad) that's good to know. (mom) i'm so excited.

welcome back. our breaking news this hour, the deadly shooting at ft. hood, texas, military base. >> identified as ivan lopez, who fatally shot himself after being confronted by police. >> and the base commander said

he served in iraq and was undergoing evaluation for ptsd. the nearby town of killeen, texas, i asked dan what he thought about it. >> it was just like a kick in the gut. made me sad and angry. made me want to do something to help. our city was offered immediately, all the assistance we could in terms of ambulances and police. our resources. and, but, it just felt like, you

wanted to do more. i wanted to call and give my condolenc condolences. but i knew he was busy so i didn't. these are real professionals in ft. hood. they know what they're doing. they need our moral support. they need us to stand shoulder to shoulder with them and express our love and respect for them. and that's what we're going to do. >> quite a number of difficult days to some, no doubt. >> there will be funerals, grieving. families learning about their loved ones in critical condition

in the hospital. i hope that all your listeners will pray for a speedy recovery for the injured, and for solace for the families of those who were killed. another tragedy we continue to follow. authorities searching for flight 370 are eliminating areas where nothing has been found. >> moving closer to australia. >> officials now concede that the mystery may never be solved. >> and officials saying that the pilots and passengers have been cleared of anything criminal,

but nothing about the crew. >> and there was a press conference a short time ago with the australian and malaysian prime ministers. >> this is the most difficult searches ever attempted. it's extraordinairely a most inaccessible spot. >> many families grieving. i can't imagine what they're going through. but i can promise them that we will not -- >> so, you can track a smartphone, packages sent in the mail. everything. so, how is it that a boeing 777 can vanish?

the ntsb is urging the aviation industry to improve the tracking of planes. >> reporter: we want find it. because the transponder was shut down or failed, search teams are searching millions of square miles. tech-savvy people wonder why. >> we need to be in the position to track aircraft though their flights. we need to look at the best, most effective way, of tracking aircraft. >> reporter: and the families only make it more urgent.

>> you can track continuously through any trip. >> reporter: as flight 370's disappearance became a global talking about, so did inadequacies in security. the two young man who boarded the flight with stolen passports. >> well, it's government's role to make sure that people aren't traveling on fake or stolen, invalid passports. border control is a government activity. >> reporter: interpol says it takes just 40 seconds to make sure a passport isn't stolen.

>> this was jim clancy reporting. and the task force trying to improve tracking of international aircraft. it's hard to imagine the suffering the families are going through. husbands, mothers, fathers, wives, children, gone in an instant. some accept it. others are holding out for a miracle. >> she has been flying with malaysian airlines for 18 years. a lovely wife and a caring mom

for my two qukids. yeah. [ speaking foreign language ] >> she's the glue that holds things together, my sister. it's a roller coaster ride. it's difficult for the families. we're hoping there will be survivo survivors. if it ended in the indian ocean, we hope there are survivors. we hope that there is a light at the end of this tunnel. >> i definitely miss her. she's a very committed, professional pilot. if something had happened to this flight, i would think, in

fact, i would believe that he would have made sure of the safety of the flight than himself. so, i'm praying not just for the pilot's family but the rest of the passengers and crew. >> and of course, the police chief saying we may never know. >> hard for the families to hear. not one shred of evidences though. tsunami warnings were briefly issued after the after shock in chile. >> coming after the massive 8.2

that shook the area yesterday. >> and back for a close look at the after shocks. last night, a 6.2. now this one, magnitude 7.0. i thought they would decrease. >> well, the intensity does not necessarily decrease. but this 7.6 came in initially at 7.8. the depth at 40 kilometer. so, 25 miles deep. ten or so miles south of the region. population, about 180,000. very densely populated. so, the usgs saying that at

least 160,000 people felt it. now 48 after shocks. and almost all of them have been offshore. so, south of the most populated city in this region, that region seeing this aftershock late in the overnight hours. and based on an 8.0 earthquake. now two in the 6.0 category. and the numbers taper off. looking at what's happening in around the world. the east coast of japan from the 2010 quake, still getting after shocks. >> thank you. the latest on the deadly

shooting at ft. hood army base in texas, right after this. and tea parties. i'll have more awkward conversations than i'm equipped for, because i'm raising two girls on my own. i'll worry about the economy more than a few times before they're grown. but it's for them, so i've found a way. who matters most to you says the most about you. at massmutual we're owned by our policyowners, and they matter most to us. ready to plan for your future? we'll help you get there. you're an emailing, texting, master of the digital universe. but do you protect yourself? ♪ apparently not. when you access everything,

[ alert rings ] we continue to follow the story out of ft. hood texas, where a shooting left four people dead, including the gunman. >> and the gunman was stationed in iraq in 2011, and had

multiple issues. >> and barack obama talked about this during a visit to chicago, saying he's heart broken and that officials would get to the bottom of what happened. >> a short time ago, i spoke with tom fuentes about where the investigation goes next. as we look forward, where does this investigation go next? working out the motivation, what happened here? >> exactly. they'll try to get as many records as they can, once the shooter's identity is verified. phone calls, computer

information. talking to neighbors, family members, trying to get a picture of what sparked this act of violence. if it was politically motivated, which would make it terrorism. was it mental illness, po post-traumatic stress syndrome. they'll be trying to determine as much as possible what the trigger was. >> unlike the 2009 shooting, also at ft. hood, which was terrorism related, it appears to not be that this time. but still some issue of insider threats on u.s. military bases.

>> well, when it comes to a military base, this is where the nation's war fighters are trained. and coming from war zones around the world. they come back, asking them to turn the switch on or off, being in position for combat, to return to peaceful civilian life. so, that's often easier said than done with some people. if that's what happened here. secondly, we're talking about a place that's really a small city. with a population of 50,000 people. there are acts of violence in cities and towns around the united states. that's another aspect of it. by sheer population, crimes often are occurring. you hope it doesn't happen in a

place like a military base, but unfortunately it does. >> does the fact that it happened on a military base, does that change the investigation? >> well, the fbi would normally have primary jurisdiction. but the u.s. army and fbi have a memorandum of understanding that they will support the c.i.d. so, they will take the lead in this case. if the prosecution, if there's no other person, and if the shooter is dead, there won't be one. but it would be by the military justice system. and the fbi would be providing the support.

and the a.t.f. would provide assistance. tracing where the weapon came from. and under the u.s. system, crime on a government reservation is a federal crime. so, in this case, the state and local officials, the department of public safety and the local sheriff would provide assistance li locally as well. but if it's with a shooter that is now deceased, it becomes easier going forward. >> thank you for watching this hour. >> for our viewers in the united states, special report with don

lemon is up next. >> for everyone else, cnn news continues. see you in a moment.
