Home Video Shows Happy Natalee

(CBS)  A home video just released by Natalee Holloway's family shows her returning from a beach trip, happy, relaxed, and smiling.

This, as behavioral experts spent several hours Tuesday questioning the only suspect still in custody in the disappearance of the Alabama teen in Aruba more than two months ago. The interrogation of 17-year-old Joran van der Sloot was expected to continue Wednesday. An FBI observer sat in on Tuesday.

Holloway's mother, Beth Holloway Twitty, was expected to return to the island Wednesday.

In the video, Natalee, who's in the back seat of a car, describes herself as "Hootie" Holloway.

Looking into the camera to talk to a friend for whom the tape was being made, Holloway says, "Just sitting in the back, cruising over to my place, and you're doing an excellent job. I just want to say happy birthday. You know, you look like a new woman. And I'm sure you feel like one, too. The beach was a blast. I had the best time of my life."

On Tuesday, Natalee's father, Dave Holloway, and volunteers searched a landfill for the fifth straight day, seeking signs of her, and looking for closure.

"The main thing we want to do is find her," says Joe Houston, who's directing the search for the Texas firm EquuSearch. "Finding her alive is the ultimate objective, but second best to a searcher like me is finding her, period."
