A tragic accident or foul play? It was a story that made national headlines, and Friday night ABC News Correspondent Linzie Janis speaks exclusively to Nathan Carman about his rescue from the ill-fated fishing trip that claimed his mother’s life. Nathan claims it was an accident that sunk his fishing boat, but authorities are still investigating the circumstances of her disappearance. On September 17, 2016, Nathan and his mother, Linda, left a Rhode Island marina sailing far out to sea to fish for tuna. When they did not return, the Coast Guard sent out a search team. Seven days later a freighter rescued Nathan from a small life raft, but Linda was nowhere to be found. Nathan claims that after the boat made a “funny” noise, began to take on water and started to sink. He was not able to find his mother, and he never saw her again. Janis’ report also includes interviews with Captain Zhao Hengdong, captain of the freighter that rescued Nathan; psychologist Dr. Rebecca Sachs; Captain Dave McCormick, who is familiar with the Rhode Island marina; Mike Iozzi, a regular visitor to the area and more.
