When Dave Holloway turned to the waters off Aruba in 2007, he was pursuing a possibility that had haunted the family since Natalee disappeared: that the answer might lie somewhere beneath the Caribbean Sea. The effort was not a routine police search. It was a privately supported expedition that brought together a boat, divers, sonar equipment and technology designed to map and inspect the ocean floor. Its story is distinct from the wider history of searches across Aruba: it shows how a father, facing years without a reliable account of what happened, tried to investigate a difficult underwater environment when conventional leads had failed.
Natalee, an 18-year-old from Alabama, disappeared during a high-school graduation trip to Aruba in May 2005. Her remains have never been recovered. Netflix’s 2026 documentary Taken: Natalee Holloway revisits the long investigation, but the 2007 expedition deserves attention on its own terms: what prompted it, what equipment was brought in, what the team reported seeing, and why the search did not produce an identification. Netflix Tudum’s documentary overview confirms that Natalee’s remains remain missing.
Why Dave Holloway looked beneath the surface
By late 2007, the case had already generated extensive searches on land and at sea, repeated interviews and several rounds of arrests and releases. A renewed arrest of Joran van der Sloot and the Kalpoe brothers in November 2007 briefly raised hopes that investigators might finally establish what happened. Dave Holloway told the Associated Press that he believed Natalee could have been disposed of in deeper water, beyond the depths covered by earlier official searches.
That was a working belief, not a proven account of where Natalee was. The distinction matters. In a missing-person investigation, a theory can guide where searchers look, but it cannot establish what happened without evidence. Holloway’s decision to pursue a private expedition reflected the family’s need to test a possibility that had not been resolved by the searches conducted up to that point.
The privately supported expedition and its equipment
In a November 22, 2007 report, CBS News, citing the Associated Press, said a private boat owner was providing divers, sonar equipment and the ability to map the ocean floor. Holloway said the team would search waters off Aruba and that he would notify local police if anything relevant was found. The plan combined human divers with tools that could help locate objects or unusual features in an underwater area too large and deep to inspect casually.
Sonar can help search teams identify shapes or changes on the seabed; mapping equipment can help them return to a specific location; and divers or remotely operated equipment can inspect a target more closely. None of those tools identifies human remains by itself. An underwater image or sonar return is a lead that needs careful examination and, if material is recovered, appropriate forensic testing.
The CBS/AP report noted that authorities had searched to depths of about 330 feet. Holloway believed a deeper search was warranted, based on conversations with a police official and a private forensic expert. That belief framed the private effort, but it did not establish that Natalee was in deeper water or that the search area contained her remains.
The search produced a troubling image, not an identification
Later accounts of the expedition describe a sequence of observations that briefly appeared promising. E! News’ retrospective on the case reports that the boat, named Persistence, located what looked like a fishing trap roughly 90 feet below the surface in December 2007. A remotely operated vehicle was sent down to examine it, and the team thought an object might resemble a skull. A diver subsequently entered the water with Aruban police divers, but the inspection did not find anything connected to Natalee.
This is an important point in the story. A shape that resembles a skull in an underwater image is not a forensic identification. Visibility, lighting, perspective, marine growth and the limits of camera equipment can all affect what an object appears to be. The follow-up dive did not confirm the hopeful interpretation, and the expedition did not recover remains identified as Natalee’s.
Dave later recalled the emotional strain of another lead that did not produce an answer. The expedition’s failure was not simply a technical setback; it meant the family was still left without the one thing it needed most: reliable knowledge of where Natalee was and what had happened to her.
How this expedition differs from other searches
Natalee’s case involved many different kinds of searches and leads over the years. The private deep-sea expedition should not be blended together with the initial island-wide search in 2005, the 2010 investigation prompted by an underwater photograph, or the separate 2017 effort in which Dave and a private investigator examined a lead involving possible human bone fragments.
Those episodes had different origins, methods and evidentiary outcomes. In March 2010, for example, Aruban police searched after vacationers reported an underwater photograph they thought might show remains; authorities did not find the pictured items and said the image likely showed coral. In 2017, a separate investigation led to testing of bone fragments, but those fragments were not established as Natalee’s remains. Keeping these episodes separate prevents an inaccurate impression that one continuous search produced a confirmed discovery.
What the 2023 confession changed — and what it did not
In October 2023, van der Sloot pleaded guilty in Alabama to federal extortion and wire-fraud charges arising from his attempt to obtain money from Natalee’s mother in exchange for information. During the proceedings, he gave an account admitting that he killed Natalee and described pushing her body into the sea. The federal guilty plea was for extortion and wire fraud, not a U.S. murder conviction for Natalee’s death. The Associated Press reported that her remains had still not been found.
The account gave the family and investigators information about what van der Sloot said happened, but it did not lead to the recovery of Natalee’s remains. It also does not retroactively turn the 2007 underwater observations into evidence. The private expedition remains a documented attempt to search a particular area of ocean; its apparent target was not confirmed as human remains.
Why the deep-sea search still matters
The 2007 expedition illustrates the difference between searching and finding. The team invested resources, used specialized equipment and followed a lead that appeared significant at first. But the standard for a meaningful discovery is not whether an image looks persuasive or whether a family has reason to hope. It is whether investigators can verify what was found and establish its relevance through reliable evidence.
For readers revisiting the case through Taken: Natalee Holloway, the expedition also provides context for the years of uncertainty experienced by Dave and the rest of Natalee’s family. It shows how the search extended beyond the shoreline and how each new possibility carried the risk of renewed disappointment. The most accurate conclusion remains a difficult one: despite years of investigation and multiple search efforts, Natalee’s remains have not been recovered.
Frequently asked questions
When did Dave Holloway organize the private deep-sea search?
The best-documented private expedition took place in November and December 2007, after renewed arrests in the case. CBS/AP reported on the plan on November 22, 2007.
What equipment did the private search use?
Contemporary reporting said the expedition had divers, sonar equipment and ocean-floor mapping capability. Later accounts describe the use of a remotely operated vehicle to inspect an underwater target.
Did the deep-sea search find Natalee Holloway’s remains?
No. A target that appeared potentially significant was inspected, but the dive did not find anything connected to Natalee. Her remains have never been recovered.
Was the 2007 expedition the same as the 2010 or 2017 searches?
No. The 2007 private deep-sea expedition, the 2010 search prompted by an underwater photograph, and the 2017 investigation involving possible bone fragments were separate efforts with different leads and outcomes.
Did Joran van der Sloot’s 2023 guilty plea locate Natalee’s remains?
No. Van der Sloot pleaded guilty to federal extortion and wire-fraud charges and gave an account admitting that he killed Natalee. Her remains were not recovered as a result of that proceeding.
