Search fails to find teen missing at sea CAPTAIN COOK, Hawaii, July 6 (UPI) -- Searchers Friday had yet to find a New York state teenager swept out to sea off Hawaii's Big Island, a U.S. Coast Guard official said. Tyler Madoff, 15, of White Plains was swept off Kealakekua Bay by large waves Wednesday afternoon, Hawaii News Now reported. The U.S. Coast Guard, Hawaii County Fire and some volunteers had searched more than 10 miles of the sea surrounding the bay, officials said. "He was seen drifting out by the hike, the members of the hike," Coast Guard Lt. Leigh Cotterell said. They tried to rescue him, but they weren't successful. Madoff was on a kayaking outing with a group of 11 other teens and two counselors when he and another boy about the same age from Florida were swept away. They were hiking on the trail. They were 30 feet inside of the trail. A wave just came up and just picked this group up. Just a freak set. A tragedy," said Rufus Duarte, who witnessed the rescue efforts. Rescuers reached the Florida teen, who was flown to a hospital on Oahu, where he was in critical condition, officials said. Big Island Now reported Friday the extensive search for Madoff had yet to yield any results. The search Friday involved firefighters blanketing the shoreline and rescue divers making five dives from the shoreline to a depth of 100 feet, said Capt. Chad Toyomura of the Captain Cook fire station.
