Coast Guard units are no longer searching for a man who made a Tuesday night distress call from near Cape Lookout, according to a Coast Guard spokesman.
However, the search-and-rescue case remains open, the spokesman said.
Morehead City Police officers are searching Crystal Coast boat ramps for any signs of boat trailers that have been left overnight, the spokesman said.
Police will report their findings to Coast Guard command officials, who will then decide how to proceed.
This follows a search that began at approximately 10:30 p.m. Tuesday.
A man reported via VHF radio that his boat was sinking on the ocean side of Shackleford Island, near Cape Lookout.
He was several hundred yards off shore and said during a mayday call that he would wade to shore.
"She's going down, she's going down," the man said in an emergency message, referring to his boat.
Coast Guard crews, including a 110-foot cutter and a search-and-rescue helicopter, searched throughout the night into Wednesday.
Asked if the case is being investigated as a possible hoax, the Coast Guard spokesperson said the case was being treated as a real situation.
The man's distress call is attached to this story.
Anyone with information on the man's identity is asked to call the Coast Guard at (910) 343-3880.
