10 years later, new witness emerges in Natalee Holloway’s disappearance

ARUBA (WBRC) - Ten years after Natalee Holloway’s disappearance in Aruba, a witness has come forward claiming he was the last person to see the 18-year-old Mountain Brook student.

Jurrien de Jong lives in Amsterdam. He told Inside Edition that he saw Joran van der Sloot, the main suspect in Holloway’s disappearance, kill her at a construction site.

"I saw that Joran was chasing Natalee into a small building under construction. In about five minutes he came out with Natalee in his arms, and slammed the body of Natalee on the floor, and then he made an opening in the crawl space...I knew she was dead," de Jong told Inside Edition.

De Jong said he didn't call police at the time because he was involved in illegal activities.

Authorities have believed that Holloway's body was dumped into the ocean. Inside Edition says the site where de Jong claims to have seen van der Sloot and Holloway is now the Marriott Surf Club. Dave Holloway, Natalee's father, was curious enough about de Jong's claims that he hired a private investigator to look in to de Jong's claims. Inside Edition flat out asked de Jong if he was lying.

"If I was making this up, it would be the work of a man who was insane. I don't consider myself insane," de Jong said.

Dave Holloway also hired a search and rescue expert, Tracy Sargent, to search the Marriott Surf Club with the help of cadaver dog, Chance. Chance did not find a trace of a human body. According to Inside Edition, the Aruban prosecutor's office is reopening Holloway's case based on de Jong's statements. The office said it could be months before their findings are revealed.
