However, Capt. Mark Fedor said the search would continue in the meantime and has been a "true all hands on deck effort."
He said the Coast Guard took into consideration Perry Cohen's and Austin Stephanos' age, both 14, their lengthy experience on the water and their "will to live" in keeping the search going so long.
He expressed his "heartfelt condolences" and called the case "excruciating and gut-wrenching."
