Dateline NBC released a new video Friday previewing Sunday's episode detailing the kidnapping and slaying of Pulaski County Realtor Beverly Carter.
The clip focuses on an interview with Beverly Carter's husband, Carl Carter, just after his wife disappeared while showing a house.
When Beverly Carter didn't return for dinner, her husband began to worry and went to check on her at the home she was showing in England, he recalls in the clip.
"If she's over there, her car will be there," Carl Carter said in the video. "Well, I drove around over there, and there was her car."
But Beverly Carter wasn't in the house.
"I thought it was weird because Beverly wouldn't leave unless she was in her car," Carl Carter added.
The video was the third clip the network has released ahead of Sunday's episode, which will air at 9 p.m. Pulaski County Detective Jeff Allison and KARK reporter Shannon Miller have also been featured in previous clips.
The episode, titled "The Client" and reported by Andrea Canning, was scheduled to air last month but was postponed.
Arron Lewis was convicted in Carter's death and sentenced to two terms of life in prison at a January trial.
