we want to welcome our viewers in the u.s. and around the world. here are the stories we are following for you right now on cnn. in the search for malaysian airlines flight 370, the hms echo is moving to the northern end of the search area supporting australia s ocean shield focusing on the area where four suspected pings have been picked up. authorities in pennsylvania say 16-year-old alex hribal went on a stabbing rampage at his high school wednesday. they don t know why. police say 20 students and one adult was stabbed in the attack. doctors say some of the injuries are life threatening. the teen is being charged as an adult. 92 seats in india s parliament decided as indians head to the poles fls today. the indian capital region among 14 states where people are casting their ballots. the country s five week marathon vote began monday and continues
they can t do both operations at once. once they dedicate the ship to running the operations, the ship will have to acquire bottom lock and actually acts as its own gps for lack of a better analogy. it is a little bit more complicated than that. but it needs to be there because its an hour-plus journey to the bottom and without the boat it loses its way. van, assuming the plane is in this location, if authorities had been looking in this area a month ago would they have likely found debris? i think, yes, i don t know of any other modern aviation accident at sea like this that we didn t find the debris field. normally you find the debris field and it leads you to the pingers. this is the only case where we found the pingers and you leads you to the surface of the debris field. i think whatever is there has now long since dispersed. and it will be very hard to
welcome back to this special prime time edition of the lead, i m jake tapper. continuing our stories, emotions have been involved with the missing flight 370. just as it seems they re close to finds out what happened to their loved ones, hopes are dashed by the changing satellite data or the cruel reality that what looked like plane debris was little more than ocean trash. after more than a month of heart ache, is this finally the breakthrough that we ve all been waiting for? what we have been picking up is a great lead. two fresh signals picked up by australia s ocean shield ship brought fresh hope for answers and perhaps closure for a search nearly exhausted by false promise. we will find the aircraft or what is left of the aircraft in
welcome back to a special prime time edition of the lead. i m jake tapper. and what was once a sprawling search area has now been hacked down dramatically thanks to two fresh sets of pings, echoing from deep underneath the indian ocean. i want to bring in cnn s tom foreman. tom, every ping gets them closer. just how close could they are right now to zeroing in to the search pings? well, jake if we believe what they re seeing, we could get a lot less than the 3 million they re talking about. this is how they have done it. if you go flying in along the satellite arc up here and you follow the actual course that the ocean shield was traveling when it picked up these pings, this is where they occurred. this is what that ship did at that time. now bear in mind that satellite tract that we have been talking about so much goes right along
desperate. the underwater search has been continuing around the clock. so far, though, nothing. today, australia s ocean shield, the ship that heard pings over the weekend is at the northern end of the defined search area. and at the south, the chinese ship haixun 01 which also believes it heard pings over the weekend, which by definition would be unrelated because they re hundreds of miles apart. the british ship hms echo is joining the search. it s been two days since searchers on the ocean shield believe began at the north came from the plane s black boxes. they have not been able to reacquire the pings. they have heard nothing, and they have found nothing. and time is fading fast. we re on day 33 now of the search. black boxes would have to be incredibly resilient to be working at a very audible level at this point. we ve seen the search area shift, expand so many times. look at this map. just look at this map. now, you might say it s a miracle given that it could have been within
