Authorities Execute Search Warrant at Rescued Man’s Vermont Home: UPDATE

MIDDLETOWN, CT — While Middletown native Nathan Carman, 22, was aboard a freighter on his way to Boston to meet up with the Coast Guard and be reunited with his family after being lost at sea for a week, authorities were executing a search warrant at his home in Vermont on Monday night, according to NBC Connecticut.

Carman traveled with the “Orient Lucky” freighter that spotted him on Sunday afternoon about 100 miles south of Martha’s Vineyard. His mother, 54-year-old Linda Carman, of Middletown, still hasn’t been found and is presumed dead, according to officials.

NBC Connecticut reports police in Vermont seized a modem with cable, SIM card and a letter written by Carman from the home.

The Hartford Courant reports that the search warrant was obtained as part of the missing person investigation, which revealed that Nathan Carman’s boat was in need of mechanical repair and he had been conducting a portion of the repairs himself and could have potentially made the boat unsafe for operation.

In the warrant, police believed they could find evidence in Carman's house that would support a charge of "operating so as to endanger, resulting in death," according to the Hartford Courant.

In audio released by the Coast Guard on Tuesday, Nathan Carman spoke with Search and Rescue Controller Richard Arsenault while he was aboard the freighter Orient Lucky and described what happened on his boat.

“Mom and I were fishing on Block Canyon and I heard a funny noise in the engine compartment. I looked and saw a lot of water. I was bringing the line and had my mom bring in the reel. I brought the safety stuff forward. And I was bringing one of the safety bags forward, the boat just dropped out from under my feet. When I saw the life raft, I did not see my mom. Have you found her?

After being informed they haven’t found her yet, Nathan Carman said “so, I got to the life raft after I got my bearings and I was whistling and calling around and I didn’t see her.”

Until Nathan was found on Sunday, Linda and Nathan hadn’t been seen since they left Ram's Point Marina in Point Judith on Sept. 18 for a fishing trip on a 31-foot aluminum center console boat, the Chicken Pox.

The Coast Guard suspended the six-day search for the pair on Friday after “exhausting all search efforts.”

Nathan Carman made a short statement to the media outside of his Vermont home on Tuesday evening and thanked the public for their "prayers and concern."
