All five people on board the recreational sub, named Titan and operated by US-based company OceanGate, were killed when the vessel imploded, which is believed to have occurred during its June 18 descent.
“Marine safety engineers with the Coast Guard’s Marine Board of Investigation (MBI) recovered and transferred remaining Titan submersible debris and evidence from the North Atlantic Ocean seafloor” on October 4, the US Coast Guard said in a statement.

“Additional presumed human remains were carefully recovered from within Titan’s debris and transported for analysis by US medical professionals,” it added.
The coast guard had also claimed to have recovered presumed human remains in June.
Debris from the Titan, which is believed to have imploded on June 18 as it made its descent, was located about 12,500 feet (3,810 meters) underwater and roughly 1,600 feet (488 meters) from the Titanic on the ocean floor. The Coast Guard led the investigation, in conjunction with several other government agencies in the US and Canada.
OceanGate is based in the US and OceanGate Expeditions, a related company that led the Titan’s dives to the Titanic, is registered in the Bahamas. The company charged passengers $250,000 each to participate in the voyage. The implosion of the Titan has raised questions about the safety of private undersea exploration operations.
