2:02 pm
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 and chaos as this stabbing spree was taking place. it lasted a little -- not much more than five minutes, according to authorities. here what happens witnesses had
2:03 pm
to say about it. >> the fire alarm went off, i was walking over towards the exit, and there was blood all over the floor. i thought maybe someone had a nose bleed or something. someone yelled she got stabbed. >> i thought it was a normal fire drill. i saw people running and screaming and crying. i thought something has to be wrong. then i saw people holding each otherness hands. i saw other people getting cut. just blood everywhere. very traumatizing. >> i told my wife one of the kids was her best friend that got stabbed, yes. and that even makes it even more difficult for what i have to say to her, you know, once i get her home. >> reporter: wolf, we've learned from many of the wounded victims here, they didn't know what was going on. they said they didn't even see the attacker coming toward them
2:04 pm
or going. all of a sudden they felt a sharp pain, many wounds went through the stomach and the torso and the back, and so everyone was really in shock as this was unfolding this morning. one student thought a fight was breaking out, only to turn around and see this student, alleged attacker, wielding two kitchen knives. we've learned three people helped subdue the alleged attacker, a school resource officer, a school security guard and assistant principal who tackled the student. in the stabbing spree. of course this is an ongoing investigation. the fbi is involved. you can bet they'll be interviewing students, there are 1200 students, around that number that attend school. interviewing students, alleged attackers' family members and figure out the motive here. according to those that knew the alleged attacker, he was a quiet student, didn't show outward signs of trouble.
2:05 pm
it has been baffling for people here in the community. they're in shock. we hope to learn more at the press conference coming up any minute. we'll hear from the governor of pennsylvania. >> i want to go to the news conference right now. the very latest coming in from outside of pittsburgh. >> i'm going to defer to sergeant -- sorry. previous history. chief seefeld from the murrysville police department, to bring you up to date on what's going on with the individual that's charged with the crime committed today. chief? >> thank you. good evening. let me begin by saying, first, i would like to thank all of our law enforcement partners from the federal level down to the local level of municipal police, as well as all ems services in our municipal and those from other surrounding areas, the school district for the cooperation, the governor for
2:06 pm
being here, thank you, and mayor brooks. about 7:13 a.m. this morning, the school resource officer, officer william buzz, our school resource full time in the schools, put out a call over the police radio stating that there was critical incident occurring and he needed assistance. at that time the murrysville police department responded to the scene. i can tell you that upon my arrival that we saw many victims in the grass area on the exterior of the building. upon entering the building we came into the scene in one hallway where we saw one of the security guards had been apparently stabbed. at that time, we assisted him with help at about the same time
2:07 pm
school resource officer had the subject handcuffed and in custody. our concern at that time, obviously, was for the welfare and the condition of all students, faculty, ems responders, police officers and so forth. i can tell you that just prior to our arrival, in according to the school resource officer, assistant principal sam king did a role that's very admirable. sam was actually able to tackle the suspect, and along with the principal from the high school, joan mellon was able to help with that. pretty much momentarily after that, he was able to get there and security the suspect.
2:08 pm
i can tell you what we saw when we got there a hallway that was pretty much in chaos, as you can imagine. a lot of evidence of blood on the floors in the hallway. we had students running about, trying to get out of the area. subsequently, upon checking and seeing what we had, immediate calls were put out to ems, locally and from surrounding areas, to get there as soon as they could, that we had multiple casualties, as well information put out and requests put out to local and surrounding police departments. our concern at that time was for the injured and those that needed help. i think everything went in a good fashion, ems was able to attend to victims rather quickly, get them either life flighted or in ambulance and
2:09 pm
transported to a medical facility. we were able to cordon off the crime scene. we brought in our investigators from the westmoreland district attorney's office, the fbi, state police, and so forth. so from federal to local levels, we've done our investigation. it's ongoing. i imagine in this investigation will continue over the next several days. the information we have right now, approximately 20 victims, 1 being the security guard. at this time we are advised that one of the victims or two of the victims are still pretty critical. our hearts and prayers go out to them. so that's -- that's the scene. the suspect was taken from the scene. what happens after that is now the ongoing investigation with
2:10 pm
crime scene processing. i can tell you that the cooperation with all 0 levels from federal down to local has been outstanding. fortunately, although this matter's very horrific, and terrific, a very bad situation, i can tell you that everything, including putting the suspect in custody, occurred rather quickly. and i would estimate that time from the time that the officer put out the call on the police radio to the time that the responders got there, and me was secured, probably a matter of five minutes. so fortunately, that's where we're at right now. the investigation continues. i'll take any questions, if there are questions. >> any word on a motive yet? bullying rumors? >> we don't have any concrete evidence but that's part of the investigation. sir, who made the call? were you alerted by 911 or how
2:11 pm
were you alerted to the emergency? >> i was alerted, and the fellow murrysville police officers were initially alerted by the call from the sro over the police portable, that he needed help. >> 911 call? >> no, school resource officer put over the radio to the murrysville police department that he needed asis tans. >> what about the suspect? >> a 16-year-old sophomore. that's what i have on him right now. >> sir, any sense of sequence of events? was he in the hallway, running down the hallway? was he going to a classroom? a lot of people are wondering how it that is someone can come into contact with roughly 20 or more people in a short period of time and carry out this attack. >> i can tell you that the crime scene is in one wing of the school.
2:12 pm
yeah, we don't know at that time, but we'll find out through interviewing, you know, the victims and witnesses, as exactly to his movement. but i can tell you, from the end of the hallway to the beginning of the hallway, that's a crime scene area and there's evidence of something occurring in that area. >> inaudible. any sense of distance? >> maybe a couple hundred feet. >> did he say anything to the officers when they arrived, school security officer? and prior to today's incident, any warning signs or red flags or were you aware of this individual? >> we were not aware of this individual, and any warning signs, things said, that will be part of the investigation, but i'm not aware of that right now. >> two knives. >> can you be more specific. >> approximately 8 to 10 inches. >> chief, can you describe, based on what witnesses said, essentially what he was doing
2:13 pm
and saying as he made his way down the hallway? >> we're still interviewing and processing that. we don't have anything that he had said that i can talk about right now. >> are these kitchen knives, hunting knives? >> straight knives. >> one more question. >> [ inaudible ] >> how long did the stabbing -- >> again, you know, we're kind of speculating a little bit on that, but prob le a matter of five minutes from the time it started until the time he was secured. >> is the suspect cooperating with police? >> i don't know that. i have not been in contact with him. >> thank you, chief. >> thank you. >> we definitely want to give you the information. we're going to be here until we answer all of your questions, but the governor's schedule is tight. we want to make sure he can express his concerns. i want to ask governor corbett
2:14 pm
to make a statement. >> thank you. first off, let me commend the efforts of not only the individuals in the school, but law enforcement, the first responders who came here ex, em various police departments, as the chief has said, from the fbi to our state police, our people in there, but also all of the local police departments. this is not something you could ever completely plan on. you certainly work on what's going to happen in a situation. but from my discussions here for the last two-plus hours, i want to commend everybody for working on this together. there are a number of heroes in this day. many of them are students. and i want you to write that. students who stayed with their friends and did not leave their
2:15 pm
friends. cafeteria workers who automatically reactively began caring for students who were bleeding. teachers and teachers' aides who pulled students out of the hallways and into rooms and began applying first aid and protecting those children. and then obviously, the school resource officer, buzz, the sergeant who was injured in this, and assistant principal joan -- i forget her last name -- mellon and sam king, who actually, between the two of them, took him into custody and disarmed him. this is, obviously, a very difficult day for this community and a very difficult day for the region of western pennsylvania, and a difficult day for the commonwealth. but also for the country. it's another sad day when the
2:16 pm
good works that a region like franklin regional and all of the good work that will the school does and school students and the excellent record that they have, attracts attention not because of the good works but because of one bad action, one very horrific five-minute period. we have received notes of condolence, calls, most recently from the governor of connecticut, dan malloy, he and i have not had a chance to connect. he's offering his assistance in any way, obviously, and you understand why with the incident that took place in connecticut a few years ago. we have a sister relationship, sister-state relationship with i'll say the region of france and received a note -- >> governor tom corbett expressing his deepest, deepest shock to what has happened in the suburban pittsburgh area today when a 16-year-old
2:17 pm
sophomore allegedly went on a stabbing spree, stabbing 19 or 20 of his fellow students as well as a security guard and, as you heard the police chief tell us, from the murrysville police department, two of those people, two of those young people are in critical condition right now. we're going to stay on top of the story. much more on this coming up. it's a shocking development in our country at this time. also another story we're following right now, there's new optimism in the search for flight 370 after two new underwater pings have been detected. also a new reason for urgency in the search. u.s. and china, they are cooperating in the airliner search, but can they overcome some deep suspicions? exclusive interview with the defense second, chuck hagel, from inside's beijing's forbidden city coming up.

2:20 pm
2:22 pm
new underwater signals and renewed optimism in the hunt for flight 370. the latest developments. a u.s. navy locator device has detected two fresh signals leaving search leaders hopeful they are those pings from the two black boxes. that optimism is boosted by a new analysis of earlier signals showing them to be consistent with flight data recorder. signals are getting weaker than could mean the pinger batteries are dying. so the focus now is detecting more pings to narrow the search area. at the same time, the hunt for debris continues. and the aircraft, they are ready to take off for another day of scanning the surface of the indian ocean.
2:23 pm
michael holmes from perth, st l australia. what is the very latest? >> reporter: yeah, wolf, we're 12 hour as head of you on the u.s. east coast. it's officially the start of day 34 of the search. as you mentioned, those recorder batteries have an estimated life of around 30 days. so, time is very tight as those batteries start to run down. >> reporter: after three long and frustrating days since the first pings were detected, crews on the ocean shield found what they were looking for. two new sets of underwater pulses, similar to the pings detected on saturday, all within 17 miles of one another. it was the strongest signal of hope since flight 370 vanished a month ago. >> i'm now optimistic that we will find the aircraft, or what
2:24 pm
is left of the aircraft in the not too distant future. >> reporter: search leaders are more confident now that the pings likely are coming from the plane's black boxes, after a new analysis of the first set of signals. the pulses are getting weaker. the first and strongest lasted two hours and 20 minutes. the newest lasted 5 1/2 minutes and then 7 minutes. >> so that means probably we're either a long way away from it or, in my view, more likely, the batteries are starting to fade. >> reporter: the batteries on the black boxes have passed a guaranteed shelf life. so every second counts. ocean shield continues to move back and forth over the search area, around the clock. towing the pinger locator, listening for signals, in water that is more than 2 1/2 miles deep. searchers say they can cover more ground that way, compared to underwater drone that will likely be launched only after
2:25 pm
they're sure the batteries powering the black box pingers are dead. >> i believe we're searching in the right area but we need to visually identify aircraft wreckage before we confirm with certainty that this is the final resting place of mh370. >> reporter: planes have been scouting for debris most every day. cnn was on board a new zealand air force p3 owe ryan as it flew. >> none of the sea craft has -- >> reporter: now, wolf, as for if they are the flight recorders or one of them, the air chief marshall, angus houston heading the search, says wreckage needs to be identified before they are certain this is the resting place of mh370. he did say, pings were sustained and consistent with a flight
2:26 pm
recorder, not some natural marine noise. he's not a man give tonight hyperbole or raising hopes. for him to say he's optimistic the aircraft wreckage will be found, it's quite something. >> the other day he was cautiously optimistic. now he's saying he's optimistic they are on to it. michael holmes, we'll check back with you. more on the search for flight 370. we'll get an update from the royal new zealand air force as they're planes are ready to take off. jim sciutto talks to chuck hagel. is he optimistic about the latest pings? full interview and more coming up. ♪ [ male announcer ] this man has an accomplished research and analytical group at his disposal.

as the underwater search sparks new optimism, the aerial hunt for debris has been a source of deep frustration. joining us by phone, andy scott of the royal new zealand air force. commander, thanks for joining us. first of all, any updates on what's going on as far as the search for debris on the surface or what's going on underwater, as far as those signals from the two black boxes are concerned? >> so, today's search is concentrating on an area approximately 250 miles separated from each other. we have the underwater search, still going on in the area and the vicinity of the pings det t detected by ocean shield and the airborne assets, 250 miles further to the west of that area for any possible drift and debris field. of course, every day the currents will go and move any potential debris as well. that of course, needs to be constantly adjusted. >> have you found any debris at all yet?
2:32 pm
>> the fly from the new zealand aircraft detected ten targets of interest. all photographed. following post-mission analysis, there was nothing to report that would link it to mh 370 regrettably. >> how surprised are you they detected pings, we hope coming from the two black boxes, but despite this massive search by nations, no debris has been spotted? is that surprising to you? >> certainly by this stage, i -- we were all hoping that we would have been spotting debris. it has gone on for obviously an unprecedented amount of time. but it is just a large area. because of of the assumptions at the start how we've got to determine the search areas, it really is still a game of time for going to keep continuing to go and update the dialer, looking at new leads and going to move those search areas for -- to cover all of the
2:33 pm
possible eventualities. >> since the four pings have been disclosed, as far as you know, commander, have any additional signals been detected yet? >> not that i've -- i'm aware of, no. what i had overnight, mainly focused around the airborne search. i haven't seen anything under the underwater one. >> the underwater one one continue as well with the towed pinger locators that the u.s. na supplied to the ship. matthew chance went up with one of the p3 teams. they flew around for, what, maybe ten hours between taking off from perth, flying out, coming back. on that trip, apparently, no specific debris, nothing significant related to the malaysian airliner was detected, is that your understanding as well? >> that is correct, yes. these are very long missions, right at the limit of range of the aircraft. yesterday's transit 3.6 hours each way, giving around 3 1/2
2:34 pm
hours on station for the aircraft. they're very long days. very long missions. and unfortunately, yesterday, no new leads. >> wing commander andy scott of the royal new zealand air force, we'll check back with you tomorrow. are there some secret tensions between the u.s. and china? the defense secretary, chuck hagel, he's in beijing. spoke exclusively. you see both with jim sciutto. the interview coming up. searchers are the most optimistic yet. but far below the surface, dark challenges await the recovery teams. how hard will it be to find and retrieve flight 370, possibly three miles below sea level? ♪ norfolk southern what's your function? ♪

now to a cnn exclusive. united states and china may be cooperating to help find malaysia air lines flight 370, but as defense secretary chuck hagel visits china, there are tensions and suspicions. our chief national security correspondent jim sciutto's traveling with secretary hagel in beijing. an exclusive interview with the secretary. live to jim right now for the very latest. how did it go, jim? >> good evening, wolf. good early morning from beijing. we were able to speak with the secretary twice, once inside the
2:40 pm
forbidden city, another sit-down as the news was coming out about the reacquisition of the pings. you speak to a lot of chinese, and many are skeptical of the search, even of u.s. involvement in the search, some conspiracy theories running around. but secretary hagel, more positive about the cooperation between the u.s./china and other countries and the broader relationship. here what happens he had to say to us. >> you could tell even -- >> reporter: we met secretary hagel inside beijing's forbidden city hours after search teams confirmed they had on two new occasions detected signals that could be coming from the missing jet. >> the head of the australia search saying he is, in his words, confident the wreckage will be found in the near future. i wonder if you share that confidence based on the information you know now. >> jim, you know the region and the immensity of this task. it's an immense search area. we think it's been narrowed, but i can't give you a forecast on what they may come up with, what
2:41 pm
they may not. there's been some new evidence here that maybe these new and emerging sounds may lead to something. but it's important we don't lift anyone's hopes, families of these passengers in an unfair way. we're doing everything possible. we will continue to do everything possible to help the malaysian airlines and malaysian government to locate the plane. >> reporter: an agonizing 33 days after flight 370 vanished, have all countries involved been doing everything possible to find the plane? >> also cases and concerns about how quickly some countries have shared their radar data, for instance, and so on. i wonder if you have concern, frustration, the search could have moved more quickly had that not happened. >> let's focus on doing everything we can, all of us, finding that plane, helping the victims, and the families, everyone who is involved here.
2:42 pm
that's where our focus should be. that's where our focus should be. plenty of time to second guess and evaluate. >> reporter: the u.s. and china, though, increasingly competitors in asia, are among the countries devoting the most military assets to the search efforts. a lot of countries involved, but also some of america's most advanced assets and some of chinas most advanced assets. an interesting collaboration. >> jim, that's a good example of how nations can cooperate. it's interesting why were they all cooperating, are they all cooperating. it's about people. it's about your people. on that flight there was about 150 chinese nationals. we had three nationals from the united states. >> reporter: in europe, however, tensions are only growing, in and around ukraine. as shown in these satellite photos, 40,000 russian troops remain on ukraine's eastern border. with fears they may be poised for an invasion, and u.s.
2:43 pm
officials already blaming russia for violence inside eastern ukraine. the penalties so far have not deterred russia. isn't it -- hasn't the u.s. and hasn't europe effectively accepted the annexation of crimea? >> no, we haven't, and we have said just the opposite that we don't accept it. >> but on the ground -- >> russia's done great damage to its standing in the world, confidence and trust in its motives. there are long-term consequences. economic sanctions will hurt russia, there's no question about it. this isn't a matter of one or two days or one or two weeks. when russia has taken action that it has to violate the integrity and the sovereign of the nation, there will be long-term consequences. long-term consequences are playing out. there may be more consequences. i don't agree that they've gotten away with this. >> are you more concerned today than you were, for instance,
2:44 pm
last week, that russia will take the next step and go into eastern ukraine? >> we're always vigilant, always looking at options that we need to take, as you know, general breedlove our supreme allied commander, tasked by nato to come up with new and additional measures and options. he will be reporting those options back to me, as well as to nato. so, we don't take anything for granted. >> those options that he's talking about are military option but was not an attack. bit moving u.s. and western assets around ukraine, in secretary hagel's words, to send a strong message to are russia. he says russia's international isolated that will have costs today, near term and long term. he believes as the cost rises russia will change its behavior, move forces back. but, wolf, as you know, we haven't seen that yet. >> not yet.
2:45 pm
jim, the u.s. and the chinese, they are both helping look for that plane, the missing malaysian airliner but also tension, as we know, behind the scenes. what are you hearing in beijing? >> reporter: you know, it's incredible, wolf. you hear so many conspiracy theories here, many directed at the u.s. talk that the u.s. is hiding information, that it really knows where this plane is. crazy conspiracy theorys about how the plane may have landed on a u.s. base in diego garcia, may have been a cia agent on the plane subject of an assassination attempt. you have these things going around, some of which show the desperation of the families frustrated with the search but some that show the tension still between the u.s. and china, tension that does exist. one positive thing, there's a lot of praise for the u.s. media over the chinese media. u.s. media pushing limits of the story more so than chinese state media is. >> jim sciutto from beijing.

challenge, wolf. the darkness,s depth of the ocean in the area, the topography all present major on straks. two more signals detected which could come from the missing plane's black boxes. now search teams are trying it refine the location. find more signals. tighten the search area. >> and hopefully in a matter of days we will be able to find something on the bottom that might confirm that this is the last resting place of mh-370. >> reporter: but the challenges still enormous. after the 2009 air france crash in the atlantic, that search area was also narrowed down, but a veteran of that operation says it was still a difficult find. >> so over a two-year period, it was probably 20 or so weeks in order to find that and had much better information. they had much better last known position and found debris on the surface. >> reporter: in the air france search, as in this one, a towed pinger locator was used.
2:52 pm
they found that plane using a similar vehicle to the bluefin-21 underwater drone that mapped the debris field. remotely operated vehicles, rovs, were then used it recover the air france wreckage. has any of the technology changed since then? >> it's pretty much the same stuff. a few upgrades. few electronic upgrades here and there. it's pretty much the same equipment. >> reporter: the sheer depth of the area now being searched is a huge challenge. the titanic was about 12,000 feet down and took searchers about seven decades to find it. the signals de s detected in th search area are 14,700 feet down, shy of 3 miles. that's the maximum depth of the ocean floor in that area and the maximum depth for the bluefin-21. rovs can easily make it that deep. but the ocean at that depth is completely dark. the bluefin and rovs will have limited visibility even with lights. and there's a potential problem with the ocean floor in that area. >> the big chunks of the plane that haven't broken up are going

to crash into the silt and dig in and this silt is quite mobile because there are microbes eating into it. it's quite porous. it's quite possible that the jet with its own pressure and the water pressure has dug into the mud at the bottom. >> reporter: experts say rovs will not be able to pick up wreckage if it's deeply buried in the silt, that mud. they say cranes run from velssss on the surface will be able to pull the wreckage out. >> thank you. let's explore with former u.s. navy oceanographer van gerley and deputy director for salvage and diving, mike dean. this depth, mike, how much does that concern you? >> the depth isn't that big of a concern to us, wolf. >> why is that? >> what's more important is the topograp topography. operating at depth is generally challenging, but if it's relatively flat, it's easy for us to maneuver around, easy for us to find wreckage and the

wreckage will stand out when they run side scan sonar. >> they haven't done topography mapping so it's like you're starting from scratch. >> a little bit, wolf. you heard the previous commentator talking about what we know about the bottom there. the good news is hms echo is nearby, fitted with the right type of gear to gi a very sort of quick ocean bottom map expedition that could be the information that would help move this faster. >> how deep can navy divers go? >> navy divers generally about 1,000 feet for man diving. >> so there's no way there's going to be anybody down -- you have to send those unmanned vehicles down there. >> no, any kind of recovery would all be done with unmanned vehicles. >> hue good are the unmanned vehicles in that kind of search that went almost three miles? >> very good, wolf. we've seen it in a number of previous expect diditions. it's very good at finding things sticking above ground. >> they have lights because it's totally dark down there.

how will they look around? >> the vehicle will be outfitted with sonar and lights as well as cameras. they'll have a visual field on where they're working. all you need to light is within the field of the manipulators. >> somebody on the surface will be table to see what the unmanned vehicles are seeing three miles down? >> yes, yes. once we put an rov in the water, the operator will have a clear field of vision to where he's operating the manipulator. >> say there are no more pings, they got pings, they think they came from the two black boxes. how long do you think it should take given the fact there's about 17 miles separating these various pings? >> well, i was one of many people last night that said at most we're probably looking at a ten-mile circle based on what we knew. nature is good at keeping us humble and that's what happened. it's a pretty big area. it's still weeks to a month, month and a half. mike may be able to refine that. based on previous work, that's what we're looking at realistical realistically. >> we have more to discuss. stand by. coming up, a critical
