CHARLENE AARON: We're learning the names of the victims

in the deadliest mass shooting in modern US history.

28-year-old Afghanistan Navy vet Chris Roybal, Hannah Ahlers,

a mother of three.

Special education teacher, Sandy Casey,

and off-duty officer Charleston Hartfield.

One of my officers was off duty attending the concert

and lost his life.

CHARLENE AARON: 59 people were killed when 64-year-old Stephen

Paddock opened fire on the crowd of some 22,000 people

at a country music concert.

CBN News reporter, Ben Kennedy, reports

from the site of the tragedy that authorities

stayed on the scene long after the attack itself.

It has been more than 24 hours since the mass shooting,

and police are still here.

In fact, you can see the flashing lights

over my shoulder.

But after the scene is clear, the pain and the sorrow

will remain.

CHARLENE AARON: This woman was in the front row

of the concert.

When I stood up from my crouched position

at the front of the stage, I could

look in a very small area, and I saw 20 bodies.

How do you comprehend that?

You don't.

CHARLENE AARON: But tales of heroism

have emerged from amidst the tragedy.

Two other off-duty officers at the concert

ran into the line of fire to help save people.

Mike McGarry was standing 200 yards from the stage

when the shots rang out.

He sacrificed himself by shielding his wife

in a group of college students standing nearby.

There was bullets flying all over.

I'm 53, they're in their 20s.

You know, I lived a decent life so far to--

I'd rather them live longer than me.

And when the call was made for volunteers

to donate blood after the massacre, people listened.

In some places, people waited in line for five hours

to give blood to those who survived.

The gunman, identified as Stephen

Paddock a 64-year-old retired accountant

from Mesquite, Nevada.

He killed himself before officers stormed his hotel

room.

While his motive is a mystery and may never be known,

authorities say he had 16 rifles and a handgun in the room.

And at his home, police found 18 more guns, explosives,

and thousands of rounds of ammunition,

as well as bomb making materials.

The FBI says claims by ISIS that Paddock was

a soldier of Islam are false.

President Trump plans to visit Vegas Wednesday,

quoting the Bible in his response to the tragedy.

Scripture teaches us the Lord is close to the brokenhearted

and saves those who are crushed in spirit.

We seek comfort in those words, for we

know that God lives in the hearts of those who grieve.

CHARLENE AARON: Christian leaders

are calling for prayers for the victims.

Carrie Underwood tweeted, "We are

praying for the victims and their families.

May the Lord bring some comfort to them."

Paula White-Cain also posted a message on Twitter,

saying, "I am praying for everyone

affected by the tragic shooting in Las Vegas.

I look to God for peace and strength."
