“Presumed human remains” were recovered from the OceanGate submersible that imploded en route to the Titanic wreckage 10 days ago, the US Coast Guard said Wednesday.

All five people on board the Titan sub were killed during its deep-sea exploration.

“United States medical professionals will conduct a formal analysis of presumed human remains that have been carefully recovered within the wreckage at the site of the incident,” the Coast Guard said in a news release.
