(NBC) — Friday on “Dateline,” when pediatric dentist Kendra Kay Hatcher is found dead in Dallas, Texas, police uncover a complex plot that leads them on an international manhunt.

Here is a preview of Keith Morrison’s report:

At the end of a lazy day, as summer shifted into September and a sinking sun threw long dark shadows across the center of Dallas, a young man named Hashem Saad had just spent the day — his day off — at home in his father’s place, a gleaming apartment building called Gables Park 17.

KEITH MORRISON: That’s a pretty nice building, huh?

HASHEM SAAD: Uh-huh. I would agree with you on that one.

Just then, 10 minutes to sunset, a white Camry made its way into the neighborhood, a young woman at the wheel. She slowed down and turned in at the entrance to her parking garage. Gables Park 17.

At precisely the moment Hashem and a friend were riding down the elevator.

HASHEM SAAD: So, we go downstairs, you know, once we get downstairs, we open up the doors

And froze.

HASHEM SAAD: You could hear just screaming.

KEITH MORRISON: Screaming?

HASHEM SAAD: Just straight– straight up screaming.

Followed, said Hashem, by the bark of some kind of gun.

KEITH MORRISON: Was it obvious that was gunshots?

HASHEM SAAD: Yeah, yeah. I knew that, like, right away. Right away. Right, when they did– it was– I was like, “really?” and then, tire screeches.

Adrenaline pumping, Hashem raced for his car and pulled out his phone, calling 911.

NAT SOUND: 911 CALLER HASHEM: Hi. Uh someone just got shot in the parking lot of the Gables Park 17. All I heard was screaming and then a loud pop and then I saw her laying on the floor.

Watch “Dateline” Friday at 8 p.m. CT on NBC4.
