A cargo ship carrying 28 crew members from the U.S. and five others from Poland vanished last week after stalling off the Bahamas as Hurricane Joaquin closed in.
On Wednesday, the Coast Guard called off the search for El Faro survivors after scouring tens of thousands of square nautical miles.
The 735-foot vessel sank during the massive storm after issuing a distress call reporting that it had lost power. The U.S. Coast Guard only found one unidentified body during the ensuing search.
While authorities have not officially identified the crew, their profiles have started to emerge in interviews with family and on social media.
