he got tackled to the ground and they stabbed him several times. i don't know how he's doing. >> reporter: police say the principal and a security guard tackled and handcuffed a knife- wielding young man. he's are not releasing his name because he's a minor. the security guard was stabbed in the scuffle. paramedics rushed the injured to the hospital. >> they were all knife wounds. most of them were to the lower abdomen. and they seem to actually almost have a pattern. most of them were to the right lower abdomen and the flight frank. >> reporter: two of the injured were in late surgery as of this morningle. all are expected to describe. students describe the suspect as shy but didn't know if he was bullied. >> and for more information, go to ktvu.com. we have raw video of the latest news conference about the stabbing. coming up in 15 minutes we'll have a live report from the scene. a major street in alameda

died. they were cooperating with police, they were questioned an released. police are looking into weather the victim was too distracted to notice her surroundings. >> she was wearing dark clothes and attempting to cross the roadway. it appears, you know, we're right in the middle of our safety campaign. one of the things we always stress to each other, if you are gonna be in the roadway always be aware. it appears she had ear bugs in her ears. maybe she was unaware and maybe didn't hear but here's still investigating and haven't determined that yet. >> reporter: police are looking at surveillance video from the mall. they talked with several witnesses as well. some people who walk or visit southshore center say they've seen too many close calls involving drivers and pedestrians. >> a lot of pedestrians. they take dangerous chances crossing the street. i don't know why they do that. but sometimes the elderly is not thinking. >> reporter: it remains unclear this afternoon if the woman was on her way to work or just out

for a walk. several residents we spoke with say there was a similar fatal pedestrian accident around the same block and around the same time last year. otis drive was closed for several hours. but reopened around 10:10 this morning. brian flores, ktvu channel 2 news. >> thank you. a family stranded in the pacific ocean with a sick toddler is back on dry land today after a lift from a navy warship. the couple and their 1 and 3- year-old daughter were in the midst of an around the world trip when their sailboat broke down 900 miles from mexico. the couple called for help when their 1-year-old got sick. they were rescued with assistance from the california air national guard, the navy and the coast guard. a house fire that started in a garage has forced four adults and a child into a hotel for the time being. the fire started just after 2:00 a.m. at a home in the 1200 block of medley court. firefighters contained the fire to the garage. they say it caused a lot of

damage to the garage and smoke damage to the home. but it can be fixed. a brand-new suv inside the garage was destroyed. fire investigators are still looking for the cause. there's growing concern about a dangerous computer bug that may be exposing the personal information of millions of people. ktvu's alex savidge explains how the so-called heartbleed bug could put you at risk. >> computer experts call this one of the most serious security flaws in recent years. hackers appear to have bypassed encryption software used by about two-thirds of the world's websites. that means if you do business on those sites your information may have been exposed. >> the vulnerability is so serious that if you know how to exploit it, you can get at users' password, credit card numbers if you were doing financial transactions on a site that used hope ssl. >> reporter: a number of websites use what's called open

ssl to hide your personal information as it moves around the internet. a number of businesses are now scrambling to upgrade their security software. that includes sites like facebook and yahoo which are putting fixes in place. >> it seems like the web community is working quickly to patch it. but for right now, check with your site. >> reporter: heartbleed was recently discovered by a security firm in finland working with google. what's troubling, it may have existed for many years before anyone realized. many users we talked to are concerned and plan to use caution on the web. >> definitely makes you worry. there's a lot of things that can happen between -- anything from personal security on your personal financing side. >> hackers can figure their way around anything. more and more people are getting the skills and electronically they would be knowledgeable. >> reporter: experts say it's unclear how the heartbleed bug originated. there's conflicting advice on

what you should do to protect yourselves. some are urging to -- some experts are urging you to change your password but others say that's not a good idea because that means logging on to sites and putting your information at risk again. a memorial service is happening right now in texas to remember the soldiers killed last wednesday during a mass shooting. this is a live look at the ceremony where you can see president obama is there speaking in his role at chief comforter, once again. he and first lady michelle obama are mourning the families. army private ivan lopez killed three soldiers and wounded 16 others before taking his own life. president obama made the same grim trip in 2009 after army major nidal hasan killed 13 people on that base. san bruno police are stepping up patrols in a neighborhood where robbers struck three times in just over 24 hours.

back now to our developing story on the school stabbing in pennsylvania -- lisa sylvester is on the scene and joins us live. lisa, have you learned anything new about the 16-year-old accused of stabbing his schoolmates? >> reporter: we actually do have some new information on that 16-year-old. we know he will be facing 20 charges of aggravated assault. they are filing these charges as a juvenile. he's 16. but in all likelihood, very, very high likelihood they will be prosecuting him eventually as an adult. he's not, our sources say, he's not cooperating with police. he's not spoken to them. we know that the family has hired an attorney. >> what about the condition of the injured? any update on that? >> reporter: well, there were

total of 20 people. 19 of them students. one of them a faculty member. of those 20 individuals, six of them are in critical condition or in the operating room. so still very significant. in fact, one of the victims was stabbed about a millimeter away, a couple of himly meters away from his heart -- millie meters away from his -- millimeters away from his heart. ese still still alive. at this point, authorities do believe all students will survive. >> what can you tell us about the community where this happened? what is this area like? >> reporter: well, murrysville, pennsylvania is a great area. it's in wed county -- in westmoreland county. middle-class area, middle-class homes. this particular area of westmoreland is actually one of the more affluent areas. this school has a great reputation where parents want their kids to go to school

which is all the more reason why people were caught offguard and surprised by all of this. >> have officials decided whether school will be held tomorrow or not? >> reporter: there is an elementary school nearby. that school will have classes. there sh a middle school that's adjacent to the high school. that will be open. but they say it will be perhaps, tleet, four days before the high school reopens in part because we're being told inside was quite a bloody scene and they have to go in and scrub the place down and clean it up. >> all right. lisa silver ster, thank you so much. police are searching for a man who kit a -- who hit a man and drove away. janine de la vega has more. >> reporter: the accident happened here on capitol expressway near seven trees. this is a heavily traveled thoroughfare during the commute hours. this accident happened at 2:00

a.m. when not a lot of people were around. that's move proving to be challenging for police. all lanes of capitol expressway were closed for five hours as officers searched for clues after a man was hit here. upon arrival officers did locate an adult male who was deceased and the investigation is ongoing. >> reporter: that man has been identified as the coroner as 26- year-old daniel campbell of san jose. police don't know where he was going or why he was there at that hour in the morning. people driving in the area near seven trees spotted campbell on the ground and called police. there was no sign of the car that hit him. >> a whole lot of police. they were everywhere and they had spotlights on the car and they were shining the car -- i guess they were looking for the car who hit the people. >> reporter: officers spent the morning canvassing the area looking for witnesses. the traffic investigation unit collected evidence to piece together how fast the car was traveling. debris was found in the road.

after inspecting it, they believe the suspect car is a 1998 to 2000 sedan with possible windshield damage. the color of the car is unknown. there's no crosswalk where the man was hit and it is poorly lit when it's dark. people in the area say they often see jaywalkers. >> it doesn't surprise me. i know a lot of friends who do the same thing. they will run across the street. some of these people are crazy drivers. >> reporter: police don't have many leads on this case. if you have any information you are asked to please call san jose police. you can do so anonymously. this is the eighth traffic fatality this year so far. there were also eight last year at this same time. reporting live from san jose, janine de la vega, ktvu channel 2 news. >> thank you, janine. more details about people killed by cars in san jose. according to research, compied by the san jose mercury news, these types of deaths are increasing. in 2013, 26 people were hit and
