The Latest on the mystery surrounding a man who was rescued at sea after floating for a week on a life raft (all times local):

A warrant used to search the home of a 22-year-old man rescued in the Atlantic after floating for a week on a life raft shows authorities are looking for evidence of reckless endangerment.

Vermont authorities said police from South Kingstown, Rhode Island, searched Nathan Carman's home in Vernon on Monday. Their search warrant indicates authorities think Carman was handling boat motor repairs himself and the vessel might not have been seaworthy.

That potentially could support an eventual charge of reckless endangerment. Carman hadn't been charged as of Wednesday morning.

The warrant says the investigation into the disappearance of Carman's mother, Linda, revealed her son "intended to go fishing further off-shore in a different location than what were his mother's intentions and understanding."

Linda Carman remains missing and presumed lost at sea.

A 22-year-old man who was rescued after a being lost at sea for a week says he feels healthy despite what he called an emotional ordeal.

Nathan Carman said outside his Vernon, Vermont, home that he's been through "a huge amount" emotionally, and he thanked the public for its "concern and prayers."

Carman and his mother, Linda Carman, of Middletown, Connecticut, left Rhode Island on a fishing trip on Sept. 18. Nathan was rescued in a life raft off the Massachusetts coast on Sunday. His mother remains missing and is presumed dead.

Coast Guard officials interviewed Nathan Carman when he arrived in Boston on Tuesday. He told them he heard a 'funny noise" in his boat's engine compartment, saw water pouring in, then lost sight of his mother before he boarded the raft.
