The investigation into the Maldives cave-diving disaster may now turn on one of the smallest but most important witnesses recovered from the deep: the divers’ computers.

A new claim circulating around the case alleges that data was manually erased from four dive computers belonging to members of the Italian group who died inside an underwater cave near Vaavu Atoll. Authorities have not publicly confirmed that any dive-computer data was deleted, and no official report has stated that the devices were tampered with.

But if such data loss is verified, it could become one of the most significant forensic developments in the case.

Five Italian divers died after entering a deep underwater cave system in the Maldives earlier this month. The final two bodies were recovered on Wednesday, May 20, bringing the search operation to an end, while Maldivian authorities said the investigation into the exact cause of the accident would continue. Reuters reported that officials are examining several possible factors, including whether the group descended deeper than planned.

The group had obtained a permit to study soft corals at the Devana Kandu site, but the fatal dive has raised questions about depth, planning, equipment, and whether every person involved was properly listed in official documents. AP reported that the divers were found deep within the cave at around 60 meters, well below the permitted recreational diving depth in the Maldives, and that at least two members of the group were not listed on the expedition documents.

That is why the alleged dive-computer issue matters.

A dive computer can record a diver’s depth, time underwater, ascent rate, decompression status, water temperature, and sometimes gas-related data. In a fatal accident, those records can help reconstruct the final minutes: how deep the divers went, how long they stayed there, whether they tried to ascend, and whether a sudden change occurred before contact was lost.

If the final 15 minutes were missing, investigators would likely ask several urgent questions.

Was the data lost because of saltwater damage?

Did the devices fail under pressure?

Were they damaged during recovery?

Was the memory overwritten or corrupted?

Or did someone access the devices before investigators secured them?

At this stage, there is no verified evidence of deliberate data deletion.

Still, the theory has gained traction because the case already contains several troubling details. The recovery operation was so dangerous that an earlier mission was suspended after a Maldivian military diver died from decompression illness. Finnish technical divers were later brought in and used advanced closed-circuit rebreathers to recover the remaining bodies from the cave.

The victims included University of Genoa professor and marine ecologist Monica Montefalcone, her daughter Giorgia Sommacal, research assistant Muriel Oddenino, marine biology graduate Federico Gualtieri, and diving instructor Gianluca Benedetti. Several of them were connected to marine research, which has fueled public speculation about what the group was documenting before the tragedy.

Forensic teams would normally compare the dive computers with other evidence: gas cylinders, regulators, dive logs, boat records, permit documents, witness statements, recovered camera footage, and autopsy findings. If computer data is incomplete, investigators may still be able to recover fragments through device forensics or compare remaining records across multiple computers.

But experts would also caution against jumping to a criminal conclusion.

Dive computers can suffer damage after prolonged exposure to saltwater, impact against rock, pressure stress, battery failure, or rough recovery conditions. Missing data does not automatically prove that someone erased it. The key forensic question would be whether the deletion pattern shows normal device failure, post-accident damage, or deliberate human access.

For now, the official investigation remains focused on the fatal cave dive itself: whether the group went too deep, whether conditions changed suddenly, whether equipment was suitable, and whether the dive was properly authorized.

But if investigators confirm that four devices lost the same critical window of data, the case could shift dramatically.

Because the last 15 minutes may show whether the divers tried to escape.

Whether they became disoriented.

Whether their gas supply failed.

Or whether something happened inside the cave that has not yet been explained.

The bodies have now been recovered from the bottom of the Maldives.

The next question is whether the machines they carried into the deep still remember what happened.
