Bodies of Four Italian Divers Recovered from Maldives Underwater Cave

On the morning of May 14, 2026, five Italian divers descended into the waters of Devana Kandu, a channel near Alimathaa island in the northeast of Vaavu Atoll, roughly 100 kilometers south of Malé. By early afternoon, none had returned. By the end of the week, all five were confirmed dead — and a Maldivian military diver who tried to recover their remains had also lost his life [1][2].

The incident is the worst single diving accident in the history of the Maldives [3], and its consequences are still unfolding: two countries have opened criminal investigations, a liveaboard operator has been shut down, and the families of the dead are demanding answers about how a group of experienced marine scientists ended up inside a cave system that, by any recognized standard, required equipment and certifications none of them appear to have held [4].

The Victims

The five who died were not casual tourists. Four of them were affiliated with the University of Genoa's ecology and marine biology programs [3]:

• Monica Montefalcone, 51, an associate professor of ecology and marine biologist at the University of Genoa [1][3]
• Giorgia Sommacal, 23, Montefalcone's daughter, a biomedical engineering student at the same university [3][5]
• Muriel Oddenino, 31, a research assistant at the University of Genoa [3]
• Federico Gualtieri, 31, a marine biology graduate and diving instructor who had recently completed a thesis on corals [3]
• Gianluca Benedetti, a diving instructor from Padua who also served as operations manager for Luxury Yacht Maldives and Albatros Top Boat, the company operating the MV Duke of York liveaboard [3][4]

A sixth member of the group, a female University of Genoa student, chose not to enter the water that day [3]. Her decision may have saved her life.

The Cave System

Devana Kandu is built around a long central reef that splits the pass into two routes, creating fast-moving drift dives with reef edges, overhangs, and a steep outer wall [6]. The cave system itself sits at the base of this structure:

• The cave entrance lies between 55 and 58 meters below the surface [3][6]
• The interior extends approximately 260 meters through three large chambers connected by narrow passageways [6][7]
• At its deepest point, the cave reaches approximately 70 meters (230 feet) [1]
• The site is associated with strong, unpredictable currents — described by local divers as "washing machine" currents capable of pulling a diver down or thrusting them upward with enough force to cause pulmonary barotrauma [8]

The Maldives enforces a recreational diving depth limit of 30 meters (98 feet) [2][4]. The cave entrance alone sits nearly twice that depth.

What Happened on May 14

The group departed from the MV Duke of York, a 36-meter liveaboard vessel that caters to both recreational and technical divers [4][9]. A yellow weather warning had been issued for the day, with rough seas and strong winds reported in the area [3].

The divers entered the water in the morning. An alarm was raised at 1:45 PM when they failed to surface [3]. Benedetti's body was recovered at 6:13 PM that evening inside what was described as the second chamber of the cave [3]. The remaining four divers were unaccounted for.

Albatros Top Boat, the Italian tour operator that managed the Duke of York, denied authorizing or having prior knowledge of the Devana Kandu cave dive [4][9]. The Maldivian government launched an investigation into why the group descended below the 30-meter limit, and the Ministry of Tourism and Civil Aviation suspended the Duke of York's operating license indefinitely [2][4].

The Recovery Operation — and a Sixth Death

The Maldives National Defence Force (MNDF) launched search and recovery operations the following day. On May 16, Sergeant Major Mohamed Mahudhee, 43, a senior MNDF diver, died from suspected decompression illness during a recovery dive into the cave [2][10]. His death underscored the extreme hazard the cave posed even to trained military divers and forced a suspension of all recovery efforts.

Three Finnish cave divers, dispatched by the Divers Alert Network (DAN), arrived in the Maldives on May 17 [11]. Equipped with closed-circuit rebreathers (CCR), high-performance diver propulsion vehicles, and fully redundant life-support configurations, the Finnish team spent a day on preparations before conducting a recovery dive on May 18 lasting approximately three hours [7][11].

Italy's Foreign Minister Antonio Tajani confirmed on May 18 that the bodies of all four remaining Italian divers had been located in the deepest sections of the cave system [5][12]. Recovery was planned in stages — two bodies on Tuesday, two on Wednesday [1].

Certifications, Equipment, and the Mismatch Question

The central question in both the Maldivian and Italian investigations is how and why the group entered an environment that demanded technical certifications and equipment they apparently did not possess.

Cave diving — the penetration of overhead environments where a direct ascent to the surface is impossible — is classified as one of the highest-risk diving activities. Under standards set by bodies such as the International Association of Nitrox and Technical Divers (IANTD) and Technical Diving International (TDI), a cave dive at the Devana Kandu site would require, at minimum, Full Cave Diver certification and technical decompression diving qualifications [3][6]. At depths exceeding 55 meters, divers breathing standard air are subject to severe nitrogen narcosis — sometimes called "rapture of the deep" — which impairs judgment and motor function. Advanced Trimix certification, which authorizes the use of helium-blended breathing gas to mitigate narcosis, would be considered standard for this depth range [3][8].

The equipment reportedly carried by the group appeared to be standard recreational gear, not the technical rigs with redundant gas supplies, reels, and primary lights that cave protocols mandate [3]. No official information has been released about the group's specific certification levels or logged cave-diving hours.

Alfonso Bolognini, president of the Italian Society of Underwater and Hyperbaric Medicine, suggested the deaths may have involved "an inadequate breathing mixture that can create a hyperoxic crisis," adding that panic at 50 meters depth could lead to "fatal mistakes" [13]. Claudio Micheletto, a pulmonologist at the University Hospital of Verona, went further, stating the evidence pointed to "not so much a depth problem, but rather [an issue with] what they breathed" [13].

Prof. Montefalcone was carrying a GoPro camera; authorities have not confirmed whether dive computers or other telemetry were recovered [3].

Proximate Cause: What the Evidence Suggests

No official cause of death has been determined. But preliminary accounts and expert analysis point to a convergence of risk factors:

Nitrogen narcosis at depth: At 50–60 meters on standard air, narcosis is profound. Judgment deteriorates, overconfidence increases, and the ability to recognize an emergency degrades [8][3].

Strong currents and weather: The yellow weather warning, combined with the site's reputation for powerful vertical currents, may have complicated both the descent and any attempt to exit the cave [3][8].

Inadequate breathing gas: If the divers used standard air rather than trimix, oxygen toxicity and narcosis would both have been elevated at depth — a combination that experts cite as one of the most dangerous scenarios in overhead-environment diving [13].

No guideline: Cave diving protocols require continuous guidelines (physical ropes) connecting the diver to the exit. There is no evidence the group deployed one [3][6].

DAN's annual fatality reports consistently identify insufficient gas supply, loss of guideline, and depth-related narcosis as the three leading contributing factors in cave diving deaths, accounting for roughly 72% of analyzed fatalities [14].

Data as of Dec 1, 2025CSV

The distribution of the bodies — Benedetti found in the second chamber on the first day, the remaining four located deeper in the cave — may indicate that Benedetti, as the most experienced diver and the group's de facto guide, either turned back or was incapacitated earlier, while the others continued or became trapped further inside [3][7]. Whether this represents a single catastrophic event (such as a silt-out or current surge affecting the entire group) or sequential failures remains unclear pending forensic analysis.

The Families Demand Answers

Carlo Sommacal, the husband of Monica Montefalcone and father of Giorgia, has publicly questioned how the dive was allowed to proceed. "My wife would never have put the life of our daughter or other kids at risk," he told reporters. "Something must have happened" [13].

The families face a jurisdictional puzzle. The Rome public prosecutor's office has opened a parallel investigation [4][10], but the dive occurred in Maldivian territorial waters, and any criminal liability for the operator or its staff would primarily fall under Maldivian law. Italy's leverage is largely diplomatic and consular. Whether Italian courts could assert jurisdiction over Albatros Top Boat — an Italian-registered company — for negligence occurring abroad is an open legal question.

The Operator: MV Duke of York and Albatros Top Boat

The MV Duke of York is marketed as a luxury dive liveaboard with capacity for technical and rebreather divers [9]. It is operated by Luxury Yacht Maldives in partnership with Albatros Top Boat, an Italian tour company. Briefings and activities aboard are conducted primarily in Italian [9].

Albatros Top Boat has denied authorizing the cave dive at Devana Kandu [4]. Whether the divers acted independently, overrode guide advice, or received some form of tacit approval from the vessel's dive staff is a central question in the investigation. The steelman case for the operator would hold that the five divers — all experienced, several with instructor-level certifications — chose to enter the cave on their own initiative, and that no operator can physically prevent certified adult divers from making that decision once in the water.

The Maldives Ministry of Tourism suspended the Duke of York's license as a "precautionary regulatory measure pending the outcome of the investigation" [2][4].

Marine Safety in the Maldives: A Broader Pattern

The Maldives receives over 1.8 million tourists annually, many drawn by its status as a premier diving destination. But the archipelago's safety record in the water has drawn scrutiny.

Local media reporting compiled by diving forums indicates that at least 112 tourists have died in marine-related incidents in the Maldives over the past six years, with 42 of those deaths involving diving or snorkeling [15]. Prior to the Devana Kandu disaster, individual fatalities — a British woman in December, a Japanese tourist the previous June — had not generated the same level of international attention [15].

Data as of May 18, 2026CSV

Comprehensive dive-fatality-rate data (deaths per 100,000 dives) for the Maldives is not publicly available, making direct comparisons with Egypt's Red Sea or Australia's Great Barrier Reef difficult. Australia's dive industry reports roughly 5–8 diving fatalities per year among an estimated 2–3 million annual dives. Egypt has experienced clusters of fatalities at sites like the Blue Hole in Dahab, but systematic per-dive rates are similarly unavailable. The absence of this data for the Maldives is itself part of the regulatory gap.

The Regulatory Question

Unlike Mexico's Yucatán cenotes — where cave systems are formally charted, restricted, and governed by certification requirements enforced at the entry point — the Maldives has no comparable framework for underwater caves [6]. The 30-meter depth limit exists as a national regulation, but enforcement at the site level depends on dive operators and their guides [2][4].

The Maldivian government's chief spokesman, Mohamed Hussain Shareef, stated that the country "has extensive water safety protocols and expert divers" [2]. But critics and safety advocates within the dive industry argue that the Devana Kandu disaster exposes a structural gap: cave systems in the Maldives are not formally surveyed, mapped, or designated as hazard zones, and there is no mandatory guide-to-diver ratio or certification verification specific to overhead environments.

What would full regulatory parity with the cenote model cost? At minimum, it would require:

• Professional surveys and mapping of all known cave systems
• Formal hazard designations with posted warnings
• Mandatory certification verification at the operator level for any overhead-environment dive
• Specific guide-to-diver ratios for penetration dives
• A regulatory body with authority to inspect and sanction operators

Operators and industry groups are split on whether such measures would reduce fatalities or simply drive uncertified divers to enter caves without any operator oversight at all — the "underground risk" argument. But the current system, in which a group of recreational divers can apparently enter a 260-meter cave system at 55 meters depth with no formal checkpoint, produced six deaths in a single week.

Italy's Diplomatic and Consular Response

Foreign Minister Tajani has been in direct contact with Italy's ambassador in Colombo, Damiano Francovigh, who also covers the Maldives, and with the honorary consul in Malé, Giorgia Marazzi [12]. Both were reportedly aboard the Maldivian Coast Guard support vessel Ghazee to monitor recovery operations [12].

Italy coordinated with DAN to bring specialist Finnish cave divers and Italian deep-sea rescue experts to the Maldives [11][12]. The Foreign Ministry has stated that "everything possible" will be done to bring the victims home [12]. Repatriation logistics remain ongoing as bodies are recovered in stages.

As of May 18, Italy has not issued a formal travel advisory or dive-safety warning specific to the Maldives. The Rome prosecutor's investigation is in its early stages [4][10].

What Comes Next

The investigation now depends on physical evidence: recovered dive computers, the GoPro footage from Montefalcone's camera, and forensic examination of the victims and their equipment. The Finnish recovery team's penetration of the cave's deepest sections may also yield information about the physical conditions inside — current patterns, silt accumulation, and passage geometry — that could clarify what happened in the final minutes.

The Maldivian government faces pressure to demonstrate that its investigation is thorough and independent. Italy, with its parallel probe and diplomatic leverage, will be watching. The dive industry is watching too: how the Maldives responds will signal whether this disaster becomes a turning point for cave-diving regulation in the Indian Ocean, or another entry in a long list of tragedies that produce condolences but not structural change.

For six families — five Italian, one Maldivian — the questions are more immediate: Why were these divers in that cave? Who, if anyone, was supposed to stop them? And what, exactly, killed them?
