I'm Lester Holt, tonight on Dateline, young, accomplished and in love, she had a whole city at her feet and a murderer outside her door.

I heard a shot. There's a guy running with a mask right in front of me.

The Alachama line just left the emergency.

There was a call of a female in the parking garage. They believed that she was shot.

The car door was open and I saw her just laying up and she wasn't moving. No, not at all.

It was devastating. I didn't see how that could even be possible.

People like Hendra don't get shot.

You're like, who is this person that just executed my sister?

On the night that we released the steal photo, he told me, I think this is my ex-girlfriend.

She was a master manipulator.

The amount of people involved in this crime shocked me.

These aren't sane individuals that can commit a murder and then make a heart out of the blood money.

How much money was it? $500. To kill somebody.

Here is Keith Morrison with 10 minutes to sunset.

At the end of a lazy day, as summer shifted into September,

and the sinking sun through long dark shadows across the center of Dallas.

The young man named Hashem Saad, who just spent the day his day off at home in his father's place.

This gleaming apartment building called Gables Park 17.

No work, no nothing. So just hanging around at the house all day.

And from here to 16-year-old eyes, the world around looked fine indeed.

Dallas Uptown, hip, young, professional, safe.

That's pretty nice building, huh?
