>> absolutely nothing. he was a quiet kid. he was nice. i mean i -- i don't -- i don't know him on a personal level. like we would talk, we were on a hockey team together. but absolutely nothing that would lead me to believe this would happen. >> what was your reaction? >> honest reaction i didn't believe it. when you hear news like this your first reaction is not to believe it, because it's shocking. but it's -- it was just hard to comprehend. and even now people are still in shock. >> what is life like at this high school? >> it's a very, very safe school. everyone gets along well, and it's one of the last places that i would guess that this could happen. >> this particular school 20 miles east of pittsburgh that's

out by monroeville, so we're talking about a superb here. describe the student body. >> are you talking ethnicities or what? >> what type of students are we talking about? middle income? >> yeah, i would say middle to high income, just -- yeah, i would say, a more -- better-off school district. >> and have you heard anything that the suspect may have said from any of the other students that may have been closer to the incident? >> i -- i have heard a few things, but i'm really not -- i'm not one to conform those. so i would really rather not say something that is not true. >> so we don't know for a fact whether there was anything that would have triggered this attack? >> exactly. >> and one final question before we lose you, did the 20 students who were stabbed by this fellow

classmate, did they have anything in common, were they part of a group that hung around each other, were they part of a team, or did it just appear as if he attacked people at random? >> i think it was completely random from what -- what happened, i would say whoever was in that particular hallway just very unfortunate. >> and richard because your parents may be listening to you on the air right now, i want to make sure you're okay? >> yes, i'm doing well. thank you. >> richard thank you very much for being with us this morning. he is a student at franklin regional high school in murrysville, pennsylvania about 20 miles east of pittsburgh. 20 students injured after a student walked into the school and began a stabbing spree. at least four of those students said to be in very serious

injury. but the doctors saying all four appear to have survivable wounds. also there has been another fatal shooting at a u.s. military base. a marine shot and killed a fellow marine with a service rifle on tuesday. they believe the marine may have accidentally fired the weapon. >> our thoughts and prayers are with all of the families involved at this point. this is being ruled an isolated incident, it is neither an act of terrorism nor an active shooter situation. president obama will attend the memorial today for the victims of the fort hood shooting. the president and fist lady will join 2,000 soldiers and the families of the victims of the shooting. ivan lopez opened fire before killing himself. and we'll bring you live

coverage of that memorial service and the president's visit to fort hood. our coverage begins this afternoon at 3:00 eastern time. more russian troops are now massing along the ukrainian border. both the u.s. and eu voicing fears of invasion which russia at this hour denies. and in eastern ukraine there have been more protests. many saying just like crimea they want to separate from ukraine. phil ittner is live in london, when you were on the ground in kiev you were among the first to report that russia is behind the protests we're seeing now. russia blames the us. what can we make of this new war of words. >> you are right. we had heard this from the ukrainian intelligence sources weeks and weeks ago that they believed that there were russian

prova pro va-- provocateurs on the ground. but russians are saying there are u.s. pro vauk tours on the ground. and of course the west saying russia is sending people in. so it's a lot of finger pointing. and are these uprising a natural occur, or is somebody manipulating the situation? >> and is there some movement on the diplomatic front? the rushing -- russian foreign minister saying they will consider talks. >> i have gotten in touch with my sources in the russian foreign minist foreign ministerry, and they are saying that sergei lavrov will at end talks.

and they will be sitting across the table from the ukrainian foreign minister and that has been a pretty rare occurrence it. it has happened once before, but it does not happen often. but also in addition to that, secretary of state john kerry will be there, and eu -- >> we seem to have lost our feed coming out of london with phil ittner. once again positive news concerning the developments coming out of ukraine. russian foreign minister saying he will meet with ukrainian officials. there's also more positive news coming out of australia in connection with missing malaysian airlines flight 370. the australian vessel ocean shield saying it heard two pings on tuesday. the transmissions are from the area where similar pings were

heard. >> reporter: the search for the missing airliner is weeks old and has already covered a vast area of the ocean. now officials believe they are much closer to finding out what happened to it. the sonar device can detect the pings sent out by a black box recorder. it heard transmissions on saturday and sunday briefly. and later on tuesday they reacquired the signals twice. >> ocean shield has now detected four transmissions in the same brood area. yesterday's signals will assist in better defining a reduced and much more manageable search area on the ocean floor. >> that is vitally important because officials say they can only deploy their submarine because they found visual evidence of wreckage. the operation to find the flight

is a multinational effort involving planes and ships from many countries. the australian government has taken the lead and is coordinating the effort. but the sheer size of the task is daunting. a search area of more than 75,000 square kilometers of ocean in depths of up to 4,000 meters, and flight recorders are not much bigger than a shoebox. but they are convinced they are looking in the right place and the signals they are hearing are from flight recorders. in south africa there has been another dramatic day of testimony in the case of oscar pistorius, who is on trial for killing his to give on valentine's day last year. he described the moment when he

realized he shot his girlfriend. >> i help hopeless, i wanted to take her to the hospital. i had my handing on her hip. i was trying to stop the bleeding. reeva -- reeva had already died whilst i was holding her before the ambulance arrived so i knew there was nothing i could do former. >> in convicted he faces life in prison. internet engineers say they discovered a major cyber security flaw, it's called the heart bleed. it's the passwords and even banking information of millions of americans may have been copromiezed. >> yes, it is possible it could be into the millions, because the companies affected are some of the biggest op line names.

but first let's break down what happened here. you know those little lock eye construction you see in web browsers, let's take banc of america for instance. that lock icon there. this heart bleed bug was able to hack past that security feature. it essentially pokes a hole in the company's security system, allowing hackers to access information. and they are able to crack the security code without much detection. the bug has affected over a half a million servers over a two-year period. what do you do? first change your pass word if the company has addressed the problem. we know in the case of yahoo and okay cupid, they have fixed

their system. but there is a test you can use. so this was created by an encryption consult act. i keyed in banc of america.com, and you can see there, all good, banc of america.com seems not affected. but this bug is so serious the department of homeland security is urging all companies to update their software and experts are urging people to be proactive and vil -individua individual -- individual.
