10/04/2014 ABC World News with Diane Sawyer

News, at the Old Bailey. In just under 20 minutes time, the rest of

the day 's news. Time now for a look at the news as seen across the

United States a couple of hours ago, in ABC World News with Dianne

Sawyer. Welcome to the news. A teenager armed with knives turns on

fellow students. Tonight, what happens as brave students and guards

try to stop him? Burning questions, as the prosecutor launches a

blistering cross`examination of Oscar Pistorius. You shot and killed

her. Tonight, new video of him on the shooting range. And overweight

and healthy? The doctor staring up at Tempest by saying stop focusing

on being thin. There is another way to thrive. `` staring up a tempest.

Good evening. It has happened again. Another quiet morning in America

shattered by a burst of violence at a school. This time, a young boy

with two knives, and a rampage inside the walls of this high school

in Pennsylvania. 15 minutes of terror. These pictures tell the

story. Frightened students, parents reuniting with their children,

police on alert, and school buses side`by`side with emergency

vehicles. Tonight we hear the stories from inside the school,

including heroes who is fast actions saved lives. Chaos this morning in

the halls of Franklin Regional High School. Just after seven o'clock,

this school of more than 1000 students, suddenly on lockdown.

A 16`year`old boy, a sophomore at the high school, running through the

halls, dressed in black. He brandished two eight inch long

knives. Teaches it started running out, people were running everywhere.

It is unbelievable. No one office and said someone is getting

stabbed. Sam King. Mr King was already in

action. Going after the attacker. He didn't have time to react, he was

right behind him. Finally the suspect was tackled on the rampage

was over. I was trying to take the knives out of his hands, but he had

a strong grip on them. The 16`year`old seemed in handcuffs and

a hospital gown. He has not yet in names. The terrifying ordeal was

less than 15 minutes from start to finish. In all, 21 students were

stabbed plus the school security officer. Ten of them are still

hospitalised, four in a critical condition. All are expected to

recover. The actions of many heroes here, students and teachers, stop

this from being much worse. And so, another of America's sons has been

added to that Valerie Young men who have descended into violence as a

nation watched in horror. He was described as a shy sophomore, but

who he is? Our correspondent with who he is? Our correspondent with

what the experts are telling us tonight. Why? Why would a high

school sophomore arm himself with knives and try to stabbed as many of

his classmates as possible? From my understanding it was random, he

didn't have any targets in mind. He was not a star athletes, not the

class president, an average kid who allegedly did something unspeakable.

Motive, unclear. Police are investigating rumours he was

bullied. It irritates incidence of mash `` it resembles incidence of

mass violence in the past. The simmering dark side of these people

who were never fully understood. We spoke to an FBI profiler. There is a

record of displaced anger and rage, building up over a number of weeks

and months until they finally believe they can't take it any more.

If you look at their background, they feel they were wrong. This case

is different, because he decided to use knives rather than guns. The use

of knives is much more personal, and intimate. Police are trying to enter

that key question of why. Why so much rage. One week we reported on

the shooting rampage at America's largest army base. Today was the

memorial of the victims of Fort Hood. President Obama paid tribute

to the three soldiers who were killed and 16 wounded, during the

second mass shooting there in less than five years. We have a renewed

commitment to keep our troops safe, not just in battle but on the home

front as well stop white then, after leaving that tribute, this image of

former president George Bush. `` as well. Then. Now to the big new hope

tonight in the search for flight 370. Again, a message heard from the

bottom of the ocean, believed to be from the black boxes. Are these the

answers to the mystery? This small device did it again. It

heard two more signals, believed to be from the black boxes stop yellow

I am optimistic we will find the aircraft, or what is left of it, in

the not too distant future stop white hot searches won't say they

have found the flight until they actually see wreckage. Here are the

four pings the distance between the first and second is 60 miles, which

is why they need more pings to narrow the search area. The signals

are man`made. A frequency other animals can't match. The second

issue is the depth. Over 1700 feet. Sperm whales don't live below 3200

feet. The Titanic was found at over 12,000 feet. The submarine is right

at the limit, at over 15,000 feet under water. Deep. Tonight,

searchers believe they are hot on the trail to solve the mystery.

Now we take you to South Africa and the murder trial of Oscar Pistorius.

Today he faced a withering cross`examination by the prosecutor

they called the wool terrier, who zeroed in on a central question from

the night he shot and killed a beautiful young Bormann. `` woman.

A cutthroat prosecutor calling for the jugular. The lead prosecutor,

known as the bull terrier, knocking Oscar Pistorius off`balance and

trying to discredit him. It will show that you are lying. Then he

played this video. That's Oscar Pistorius blasting away at

watermelons. You can hear him laughing. And saying, that is softer

than brains. Now insisting the fatal shooting of his girlfriend Reeva

Steenkamp in the bathroom of his home last year had the same effect.

He demanded Oscar Pistorius looked at Ory photographs of her. The

gallery was gasping. Reeva Steenkamp's family unable to look.

It was clear the prosecutor's primary line of attack was the

inconsistencies in his account of what happened. Oscar Pistorius once

said killing Reeva Steenkamp was the accident but now says his gun going

off was the accident. Oscar Pistorius was grilled mercilessly

today. But what the prosecution didn't get too was the door. Why did

he shoot for bullets into it if he says he did not intend to kill

anyone? Why did he wait five minutes before battering down the door to

find Reeva Steenkamp inside? And why didn't he make sure she was safe

before he started shooting? The answers to those questions could

spell the difference between an accident and murder.

Also tonight, Toyota announced a massive recall today, 6.4 million

cars worldwide. 1.8 million in the US. They have cited five different

defects, including airbags that don't deploy and seats that shift

without warning. There are 27 models on the list and we put them on our

website for you to check. There is a crisis unfolding tonight halfway

around the world. Hundreds of thousands of people calling for the

attention of anyone who can help. It is happening in the Central African

Republic. Families caught in the violence between Christians and

Muslims. Tonight, our Chief foreign correspondent takes us there inside

the crisis point. What has been unleashed here is

terrifying. No one knows the death toll. Because the killing is too

frenzied and to widespread to count. Up to 700,000 people have been

driven from their homes. Nearly 100,000 innocent people and their

families have fled from warring militias and gathered here at the

main airport, desperate for protection. These people and the

country forgotten by the world. There are so many conflicts flaring

up, it's hard for them to get attention. So the bloodshed

continues and they swelled under the sun. Across this rather why you

offence, put there for their safety the authorities say, they tell us in

French have a fled for their lives the night of the killing started.

Someone came to your house? With the guns? That came with guns? In the

heart of Africa, this is one of the poorest countries in the world.

About 4 million people now making war on each other across religious

lines. Muslims attacking Christians, Christians responded with

unspeakable ferocity. The killers brandishing their machetes and

knives with glee. There are several thousand international peacekeepers

here but they are overwhelmed. 25 have been killed. Others have

allegedly joined in a masculine. Today, a visit by Samantha Power, US

Ambassador to the UN, trying to mobilise the world to stop the

genocide. `` joined in the massacre. We need to raise the resources to

help people. An astonishing moment captures the desperation. An

investigator with Human Rights Watch hears the sound of a baby crying in

the bush. In the middle of nowhere... Abandoned but alive. Like

her country, as it descends into hell.

Up next, a new and surprising look at real health. A doctor saying you

don't always have to lose weight. Tonight, the big debate over a new

approach to living a healthy life. There is a new debate under way

about health. It is said to threats of us are overweight or obese but is

it possible to be overweight and healthy? Are the times being `` over

weight helps? One cardiologist says it is time to change the focus from

being thin. Meet 61`year`old Roger who had a

heart attack 20 years ago. Today, at 191 pounds, he is still overweight

but his doctors say not to shed the pounds. FAQ is not always the devil.

It is a radical point of view in our society, where the body Mass index

determines how overweight you are. Roger is 29.4. The doctor in

Louisiana warns Americans to stop fearing fact. Leinbach is in the NFL

would be considered obese. `` linebackers. But they are all

muscle. He has written a book about focusing on fitness, not thinness.

Hello it is important to be fit, not thin, if you want to improve

long`term health. `` it is more important. Roger can walk one mile

in less than 15 minutes, works out every week and makes an effort to

stay active. The doctor says if you are fit and fat that's better than

being and unfit. You research it shows under people were 70% more

likely to die early than those battling obesity. If they are

underweight, they don't have the reserve. In some ways, having more

fat might help a person being able to fight disease. Especially serious

diseases that cause debilitating weight loss. And what about the

added strain on your heart while exercising when overweight? It is

set to start `` she says to start early. It is located gives people

that hope? I am trying not to promote obesity. But it isn't

doomsday. If they don't lose that last 30 or 20 pounds, they can still

be healthy. They might not be thin on the outside but like Roger they

can know they are fit the inside. Hillary Clinton and a new clue about

2016. She says she is deeply flattered and she is thinking about

running for president. She will continue to think about it for a

while. Staging. In the meantime, on June ten she is releasing a new book

about her time as Secretary of about her time as Secretary of

State. And a picture show from around the world. Can you guess what

are? Every block of colour is a burst of children is seen above the

Netherlands. What is wrong with this picture? The cover of Rolling Stone.

It is making headlines, not just for obvious reasons, but because of

this. John Hancock did not sign the Constitution. He signed the

declaration of independence. We did she looks great, anyway. Finally,

what does it take to steal the spotlight from Britain's glamorous

royal couple? Some chubby cheeks and persistent curiosity. We are talking

about tiny Prince George on his first royal tour in New Zealand. The

most watched Claygate Avenue. It was the first official order of

princely business. `` playdate ever. Eight`month`old baby George holding

court with ten New Zealand babies his own age. They will all grow up

to be his royal subjects. The future king was most interested in his

mother's head, not so much blocks. He has some work to do when it comes

to the ladies. This little girl burst into tears when he tried to

hold hands. She might regret that one day. Prince William told the

other first`time parents in the room that baby George is now teething and

that he is the one to give him a bottle every night and put into.

See you next time. We thank you for watching.

If you are enjoying the weather, you will be pleased with the outlook for

the next few days. Lots of dry weather about. The days will be mild

and fairly warm. At night, still cold and a touch of frost at
