But, miles from the MA shore, crew members on the Chinese freighter Orient Lucky caught sight of Carman in his inflatable raft.On Sept. 28, police release the search warrant affidavit into Nathan Carman’s home.”Clearly something happened, but I don’t know what, and I don’t know how it could have been prevented”, he said. Nathan was rescued in a life raft off the MA coast on Sunday.A witness told police that Carman removed the trim tabs – which correct listing, or tilting, and help a vessel operate as intended over a broad range of water conditions – from his boat and patched the holes with a marine sealant, the warrant said.Nathan Carman was brought to the Coast Guard’s base in Boston Tuesday morning, where he was reunited with his father, according to the Coast Guard. Although Santos would not reveal what Carman said in the interview with the Coast Guard, he did say that this was “a tragic accident”.The 22-year-old man who survived a week at sea after a boating accident vehemently denied Wednesday that he did anything deliberately unsafe during the offshore tuna fishing trip that led to his mother’s presumed death and has sparked a criminal investigation. Nathan Carman told the U.S. Coast Guard he and his mother, Linda, were fishing when they experienced engine trouble and their boat took on water. He has not been charged with anything.Twenty-two-year-old Nathan Carman told The Associated Press on Wednesday that the fishing boat he was in with his mother sank within a matter of minutes. He said he blew a whistle and called out frantically for her for hours.”When I saw the life raft, I did not see my mom. Mom!'” Carman said. He added: “I loved my mother and my mother loved me”.Authorities say Carman was a suspect in the unsolved 2013 slaying of his 87-year-old grandfather.A 2014 search warrant obtained by The Associated Press said that Carman had dinner with his grandfather the night before and was the last person known to have seen him alive; that Carman had bought a rifle consistent with the one used in the crime; and that he discarded his hard drive and Global Positioning System unit used around the time of the shooting.Police said in an affidavit they learned Carman had purchased a Sig Sauger 716 patrol.308 rifle from a gun store in New Hampshire – that he never told police about – that matched the size of round used in the murder. An arrest warrant was submitted to a prosecutor in 2014, but was returned unsigned to police with a request for further information.Chakalos was wealthy. He left his estate, worth tens of millions of dollars, to Nathan’s mother, Linda, and his other three daughters.”He loved me very dearly”, said Carman.The chief state’s attorney’s cold case unit is assisting Windsor police in the investigation but no arrests have been made in the murder, authorities said.His mother was in the cockpit, he said. But when he looked back, his mother was no longer there, he said.’They went fishing – that was one of their bonding things.Carman was found in good health in a life raft, two days after a Coast Guard search had been called off. Police searched his home Tuesday as part of the investigation into the incident, but he has not been charged with anything, the Associated Press reports. Their search warrant indicates authorities think Carman was handling boat motor repairs himself and the vessel might not have been seaworthy. According to media reports, the request for a search warrant indicates that investigators believe Carman may have purposely taken his mother out on a vessel in sore need of fix and to a different location than he led her to believe.The family members were fighting over Nathan Carman’s care, and there was a dispute about money, Klein said.
