Natalee Holloway Witness Comes Forward: 'I Knew She Was Dead'

Dave Holloway is back in Aruba exclusively with INSIDE EDITION searching for answers in the disappearance of his 18-year-old daughter, Natalee.

“What was it like for you when you got off that plane and set foot back in Aruba?” INSIDE EDITION’s Lisa Guerrero asked.

He said, “It was like, here we go again.”

The main suspect in Natalee’s disappearance is the notorious Joran van der Sloot. They first met at the Holiday Inn Casino where he gambled regularly and she was staying with her high school classmates on their senior trip.

They saw each other again at Carlos 'n Charlies, a popular bar. Natalee was seen leaving with van der Sloot. He was supposed to drive her back to her hotel. She was never seen again.

“Some of her classmates moved on to a different club,” David Holloway said.

A decade later the trail has gone cold, perhaps until now.

Jurrien de Jong, a citizen of the Netherlands who lives in Amsterdam, says he was one of the last people to see Natalee alive.

“I know what happened to Natalee Holloway,” he told INSIDE EDITION.

Guerrero asked, “What did you see the night Natalee Holloway went missing?”

“I saw that Joran was chasing Natalee into a small building under construction. In about 5 minutes he came out with Natalee in his arms and slammed the body of Natalee on the floor and then made an opening in a crawl space and pulled the body by the ankles inside the crawl space,” he said.

Guerrero asked, “So, you saw Joran van der Sloot slam Natalee Holloway’s body onto the ground and pull her into a crawl space?”

“Yes, by her ankles. I knew she was dead,” he replied.

Why didn't you call the police?” Guerrero asked. “

“I was between a rock and a hard place,” explained de Jong. “I saw a crime passing before my eyes but I also was at that moment busy with illegal activities, so I didn't know what to do.”

The site where the witness claims he saw all this was under construction in 2005, but is now the Marriott Surf Club, a 900 room time share resort popular with Americans.

Dave Holloway is so intrigued by the new information, he asked a private detective, TJ Ward, to accompany him to Aruba to help with the investigation and also to analyze de Jong’s voice with a technology that supposedly detects lying.

Guerrero asked Ward, “What was indicated in this program in terms of his stress level in his truthfulness?”

“He was being truthful with what he said,” Ward replied. “He was very stressed with what he said and he was embarrassed he didn't bring this forward.”

Guerrero asked, “So, you believe this witness may be credible and his story could make sense?”

“It could make sense. It could,” Dave Holloway said. “I still have my guard up because I don't want to be disappointed.”

How to check this remarkable claim? It’s long been believed her body was dumped in the ocean, but does the secret to Natalee’s disappearance lie somewhere in this beautiful oceanfront resort?

Dave Holloway sought the help of Tracy Sargent, a search and rescue expert, whose dog, “Chance,” has been trained to detect cadavers. We checked into the hotel like regular guests.

Tracy and Chance strode the grounds and pathways. They went inside stairwells and checked out the garage. Every available space open to resort guests was probed by Chance, using his amazing sense of smell.

“This dog is trained to find missing persons, specifically human remains,” Sargent said.

Even with the passage of 10 long years, to say nothing of all that concrete, Sargent says it's still possible for the dog to detect a scent.

“Were you able to find any trace of Natalee’s body?” Guerrero asked her.

“No. Not at all. Not at this point. We certainly can't rule it out,” she replied.

The new witness believes Natalee could be buried on grounds that are inaccessible to guests. Possibly beneath the laundry facility, a mechanical room near the elevator shaft or perhaps where the garbage is stored.

Guerrero asked de Jong, “People may say you are looking for attention and you are giving false hope to the family, what is your response? Are you lying?”

“If I was making this up, it would be the work of a man who was insane I don't consider myself insane,” he replied.

Guerrero then asked David Holloway, “So you’re not going to give up on this lead yet?

“No. Not at all,” He replied.

“Will you ever give up looking for Natalee?” Guerrero asked.

“No. As long as there is a chance that I’ll find her, I’ll keep looking,” said the heartbroken father.

The prosecutor in Aruba is now reopening the Holloway investigation based on de Jong's statements. He says it could be a couple of months before he reveals his findings.

Joran van der Sloot maintains his innocence in the case.
