CARL AZUZ, HOST: Hey, thank you for taking 10 minutes for cnn STUDENT NEWS.

I`m Carl Azuz.

This Wednesday, we`re starting with a tragic story involving a 26- year-old woman named Kayla Mueller. She was an aid worker from Arizona. She had traveled all over the world to work with humanitarian groups.

In August, 2013, she was taken hostage after leaving a hospital in Aleppo, Syria. The ISIS terrorist group initially demanded $7 million for

her release.

But ISIS said it did not kill Mueller. It said on Friday she had been killed in a Jordanian air strike in Syria.

The U.S. government says there`s no evidence that civilians were in the area of the strike, but that in any case, ISIS is responsible.

JOSH EARNEST, DEPUTY WHITE HOUSE PRESS SECRETARY: This, after all, is the organization that was holding her against her will. That means they

are responsible for her safety and her well-being and they are, therefore, responsible for her death.

AZUZ: Kayla Mueller`s family says her whole life was dedicated to helping people in need of freedom, justice and peace.

The next story today involves silent witnesses to events on the road - - dash cameras. They`re finding uses in everything from protecting police and civilians to documenting disaster.

One recent example involves a plane crash in Taiwan. A TransAsia Airways flight had at least one engine failure last week, causing it to

clip a road and crash into a river. Forty people aboard the flight were killed. Three are still missing. But 15 survived it.

And their accounts, plus video from drivers` dash cams are helping investigators determine why the plane went down.

UNIDENTIFIED MALE: (voice-over): Dash cams seem to be everywhere. They`re cameras mounted on a vehicle`s dashboard or windshield to record

footage of the road ahead. Police have been using dash cams for years to show what takes place when they pull someone over or give chase.

UNIDENTIFIED MALE: OK, he just crushed. He just crushed.

UNIDENTIFIED MALE: But sometimes they capture unexpected incidents, like this.

Dash cams are so popular in Russia that many people don`t leave home without them. As a result, Russia`s dash came videos have become an online

phenomenon, capturing road rage, even this unbelievable video of a meteor falling from the sky.

Dash cams can protect drivers from accusations of blame in accidents, prevent insurance fraud, deter police officers from taking bribes and

potentially show proof of violent attacks from other motorists.

In the U.K., some insurance companies offer drivers who have a dash cam installed discounts on their insurance premiums.

Dash cams have captured everything from the conflict in Ukraine to bush fires in Australia. Dash cam videos may get some people in trouble,

but they can also be invaluable in finding the cause of a crash in the air and on the ground -- a small price to pay for peace of mind and a picture

of what really took place on the pavement.
