Investigators in the United States are trying to figure out whose remains they have in their possession, as part of the massive investigation into the Titan submersible implosion.
The U.S. coast guard says it will conduct a formal analysis of what it calls "presumed human remains" that have been recovered from the wreckage area of the Titan submersible.
Christine Dawood says she's unsure whether she'll be able to find closure after her husband, Shahzada Dawood, and son Suleman died aboard the Titan submersible.
