 BOSTON, Mass. -- The U.S. Coast Guard has confirmed that one of two Middletown missing boaters has been found alive. 
 
 Nathan Carman was found Sunday drifting at sea by a freighter. He was in good condition and was coming back to an undisclosed port. There was no information about the whereabouts of his mother, Linda. 
 
 The Coast Guard in Boston says Nathan Carman was found by a freighter on Sunday about 100 nautical miles south of Martha's Vineyard. 
 
 “Good to go,” Coast Guard representatives in Boston said. He was not suffering from life threatening injuries, which is why he’s staying on the freighter. 
 
 He was found on a four person inflatable life raft that is required safety equipment 
 
 The family has been notified. 
 
 Saturday night, friends held a vigil for the Carman's at Linda's home. 
 
 For about a week, the Coast Guard searched roughly 60,000 square miles for Linda Carman and her son Nathan. 
 
 Last Sunday at 6:30 p.m., the Coast Guard got a report that Linda Carman, 54, and her son Nathan, 22, both from Middletown, Connecticut, didn't return from an offshore fishing trip. They were due back Sunday at 9 a.m., a friend of Linda's said. 
 
 Nathan now lives in Vermont, but grew up in Middletown. They left from Ram's Point Marina in Point Judith, Rhode Island on Saturday evening. According to Monte Montegrio, a friend of Linda's who also lives with her, Linda and Nathan frequently meet up to go fishing since Nathan moved out, and the pair are very experienced fishers. They've traveled as far as Alaska for fishing trips in the past. 
 
 Nathan has Aspberger's syndrome and previously went missing in 2011 after the loss of his beloved horse. He was found in Virginia a few days later and was unharmed. 
 
 After that incident, Gov. Dan Malloy declared August 23 "Missing Persons Day" in the state to support families of those who have disappeared. The day was in honor of Nathan, as well as Isabella Oleschuck, another person who went missing but was found safe in 2011. The Office of the Victim Advocate said the day is intended to remind people that you do not have to wait 24 hours to file a missing persons report. ||||| BOSTON (CBS) — A man who was rescued after spending a week at sea in a life raft was debriefed by the Coast Guard Tuesday in Boston after the search for his mother was called off. Authorities also searched his home for clues. 
 
 Nathan Carman, 22, arrived safely at a Coast Guard base in Boston Tuesday morning, though his mother, Linda Carman, 54, has not been found and is presumed dead.

 Just what happened to Linda Carman was not yet known. A search warrant was executed Monday night at Nathan Carman’s Vernon, VT home. Officers seized a modem, a Garman SIM card and a letter written by Nathan. 
 
 Nathan and his mother disappeared September 18 after leaving Point Judith, Rhode Island on a fishing boat named the Chicken Pox. A week later, the Coast Guard suspended their search for the pair. 
 
 After he was questioned Tuesday, Nathan left the Coast Guard base with his father. 
 
 The Carman family has had hard times. In 2013, Linda Carman’s father was found shot to death in his Windsor, Connecticut home. That crime remains unsolved. According to WFSB, Nathan Carman was “a primary person of interest” in the murder of his grandfather. 
 
 Nathan has Asperger’s syndrome, a higher-functioning form of autism. 
 
 Five years ago, he disappeared from his home, upset over the death of his horse, and was found days later in Virginia. 
 
 A police affidavit issued to obtain the search warrant of the Vermont home “indicates that Linda and Nathan had different intentions as to the final destination of the fishing trip.” 
 
 Linda, it states, thought they were going 20 miles off shore. Nathan, according to people he spoke with before he left, had other plans to take them roughly 100 miles out. “I thought he said the canyons which are off Block Island,” said Mike Iozzi who struck up a casual conversation with Nathan hours before he left the dock. 
 
 “I didn’t see him with fishing poles,” Iozzi told WBZ-TV. “I didn’t even see him with food.” 
 
 The affidavit also stated that Nathan’s boat was in need of mechanical repair. 
 
 On Sunday, Nathan was found drifting in an inflatable raft by the Chinese freighter Orient Lucky, about 100 nautical miles south of Martha’s Vineyard. 
 
 There was no mayday call and no radio transmission of any kind from the fishing boat, according to the Coast Guard. On Tuesday, the Coast Guard released audio of their conversation with Nathan after he was rescued by the freighter. 
 
 “Mom and I, two people, myself and my mom were fishing on Block Canyon,” Nathan said. “There was a funny noise in the engine compartment, I looked and saw a lot of water.” 
 
 “I had my mom bring in the reel, I brought the safety stuff forward,” Nathan said. “I was bringing one of the safety bags forward and the boat stopped out under my feet. When I saw the life raft, I did not see my Mom. Have you found her?” 
 
 Coast Guard Search and Rescue Controller Richard Arsenault responded, “No, we haven’t been able to find her yet.” 
 
 Nathan told Arsenault that after he got to the life raft, he began whistling and calling and did not see his mom. 
 
 Linda Carman had told her close friend that she and her son would take the boat out toward Block Island for an overnight fishing trip. 
 
 “I’m hoping for lots of answers,” said Sharon Hartstein, a family friend. “I want to know if there’s still hope for Linda, I want to know where they were, and what happened.” 
 
 The Coast Guard does not believe that Linda Carman could still be alive, so the search for her was terminated.

 Nathan survived with food and water in the raft, and was in good condition. 
 
 Coast Guard Petty Officer 3rd Class Nicole Groll said there are some lingering questions after an exhaustive search that failed to locate Nathan. 
 
 “He said his boat sunk off Block Canyon, and we scoured 62,000 nautical miles of sea,” she said. “He was found in the search area, his boat went down in the search area. Why didn’t he see us? Why didn’t we see him?” 
 
 “We want to know what we can do to make our search efforts better, so, god forbid there’s another person we’re searching for, we can do the very best we can to make sure that they’re found and brought home safely,” she added. 
 
 WBZ NewsRadio 1030’s Ben Parker reports ||||| Nathan Carman told the U.S. Coast Guard that when the boat he was on with his mother started taking on water in the Atlantic Ocean and he got into a life raft, he looked for her but couldn't find her, the Coast Guard said Monday. 
 
 Carman, 22, who grew up in Middletown and now lives in Vermont, was rescued Sunday about 100 nautical miles south of Martha's Vineyard by a passing freighter. His mother, Linda Carman, 54, of Middletown, has not been located. 
 
 The two had been in a 31-foot aluminum boat, leaving Point Judith, R.I., late on Sept. 17 for a fishing trip. They did not return as scheduled Sept. 18, and the Coast Guard searched a huge area over six days for the vessel. 
 
 Nathan Carman told the Coast Guard the boat sank Sept. 18 in deep water near Block Canyon off the coast of New York, said Coast Guard Petty Officer 3rd Class Nicole Groll. When he was picked up, Linda Carman was not with him, Groll said. 
 
 When the boat started taking on water he "looked for her but did not find her," Groll said. 
 
 The Coast Guard had no plans to renew its search, suspended last Friday. Groll said the location Nathan Carman gave where the boat sank is in deep water where there is no feasible recovery option.

 Groll said the mother's disappearance was "beyond the survivability window," a determination that takes into account time passed, water conditions, the availability of food and drinkable water, and other factors. 
 
 "A decision to suspend a case is never easy," she said. "However, we are not going to reopen the search for Linda Carman." 
 
 Nathan Carman was found in a raft that had been part of the boat's safety equipment, Groll said. The area where the raft was found had been covered in the earlier search, she said. 
 
 "We searched over 62,000 nautical miles. We were extremely thorough," Groll said. "We searched until all possible avenues were exhausted." 
 
 Nathan Carman, reported to be in good condition, was picked up by the freighter Orient Lucky, now heading to Boston, Groll said. The freighter is from Shandong, China, but Groll did not know its origin or destination at the time it picked him up. 
 
 The freighter will be met by Coast Guard officials when it arrives Tuesday evening, she said. 
 
 Hartford attorney Hubert Santos said his firm also plans to have someone there. 
 
 "We are Nathan Carman's attorneys and we are trying to reach him and we plan on having someone in Boston when the boat docks," said Santos, who said he has previously represented Nathan Carman in another matter. 
 
 Santos said his office has contacted the U.S. Coast Guard as well as U.S. Attorney's offices in Connecticut and Massachusetts to let them know that whether "he needs a lawyer or not" Carman has an attorney who wants to be present before any interviews are done. 
 
 The Carmans left Port Judith, R.I., in a 32-foot aluminum boat called the Chicken Pox late on a Saturday, Sept. 17. 
 
 Nathan Carman, who grew up in Middletown and lives in Vermont, and his mother told friends they were going to Block Island to fish and would return the morning of Sept. 18. 
 
 Sharon Hartstein, Linda Carman's close friend, said Monday that family members were making arrangements to meet Nathan Carman when the Coast Guard releases him. She also said Linda Carman's family was planning to offer a reward for information about Linda and the boat "to find out what happened." 
 
 The search for the two began Sept. 18 and by Tuesday had expanded to an 11,000-square-mile area of the ocean, "roughly twice the size of Connecticut," the Coast Guard said. 
 
 Search vessels from Maine and New York and aircraft from Cape Cod and North Carolina were involved. The Coast Guard announced Friday that it was suspending the search. 
 
 Hartstein said Nathan Carman moved to Vermont in recent years and met up with his mother regularly to go fishing off the coast. 
 
 "Linda and Nathan go out at least monthly," she said. "They like to fish." 
 
 Hartstein said the two usually leave the marina late at night or early in the morning — sometimes 2 or 3 a.m. — to fish. 
 
 Hartstein said Carman's sisters were communicating regularly with the Coast Guard, and Hartstein has also been in touch with Clark Carman, Nathan's father and Linda's ex-husband, who lives in California. 
 
 Nathan Carman in 2011 was the subject of a multistate search when he unexpectedly left town at 17 years old and turned up four days later in Virginia. 
 
 Courant Staff Writers Dave Altimari and Christine Dempsey contributed to this story.
– A missing 22-year-old boater who'd been given up for dead is safe and sound aboard an ocean freighter that spotted his life raft. His mother, however, remains lost at sea. Nathan and Linda Carman went missing on Sept. 18 after setting off from Rhode Island on a fishing trip in their 32-foot boat. The Coast Guard searched more than 60,000 square nautical miles, an area bigger than Georgia, before suspending its hunt on Friday, reports CBS Boston. On Sunday, however, a freighter about 100 miles south of Martha's Vineyard picked up Nathan in a four-person inflatable raft. He's in good condition, so much so that he will remain on the ship until it reaches land on Tuesday. It remains unclear what happened or whether there's a chance 54-year-old Linda Carman is alive. "She was not in the raft," says a Coast Guard spokesperson, per the Hartford Courant. "The whole situation is under investigation." The Carmans regularly went out fishing along the coast, perhaps once a month, says a family friend. Nathan lives in Vermont and Linda in Connecticut. Nathan, who has Asperger's, was the focus of a previous search mission in 2011, reports Fox61. He disappeared at age 17 from Connecticut after the loss of his horse and turned up four days later in Virginia. In fact, Connecticut declared a Missing Person's Day after the incident, a move in honor of Nathan and a woman who went missing in a separate incident. (This boater survived thanks to skills that would have impressed MacGyver.)
