Coast Guard rescuers have shifted their focus from finding the missing cargo ship El Faro to finding survivors from what they believe was a horrific wreck. According to a report from CNN, the ship sank as it sailed through the Caribbean Sea as Hurricane Joaquin approached last week.

The search covered an area of about 225 square-miles, but days after the last communication with the vessel, no evidence of the ship’s hull has been found. Ninety-six hours after the ship made its last contact with ground controllers, the Coast Guard has found nothing but debris.

Coast Guard officials reported that so far they have located survival suits, lifeboats and rafts, but there were no signs of life. One of the survival suits contained the unidentified remains of what they believe was a crewmember.

The ship was carrying a crew of 28 Americans and five Polish citizens when radar lost track of it off the southern rim of the Bahamas Islands last week. Rescuers fear the ship was caught in the 130-mph winds of Hurricane Joaquin.

The Coast Guard continues to fly over the search area but has yet to report any sightings of survivors. Rough seas and choppy conditions prevented rescuers from spotting much until conditions improved on Sunday. The ship was on its way from Florida to San Juan, Puerto Rico when it sank.
