The Coast Guard and Air National Guard crews spent two days searching for the four before announcing the suspension Sunday night. "The decision to suspend a search and rescue case like this is never an easy one to make," said Captain Cynthia Stowe. The Coast Guard extends our deepest sympathies to the families and friends of the lost crewmen and the deceased. They will all be in our thoughts and prayers. At least one person died and three were rescued from the Low Speed Chase after it grounded near the Farallon Islands. But the remaining four people aboard remained unaccounted for.
