Four people were found dead Friday in the wreckage of a small twin-propeller airplane that went down in a remote part of the Great Dismal Swamp in southeast Virginia, state police said.

It took a day for a helicopter to spot the wreckage of the Cessna 340 that vanished Thursday while flying from Fort Lauderdale, Fla., to the Hampton Roads area, police spokeswoman Corinne Geller said.

The swamp, which straddles the Virginia-North Carolina border, is one of the last large wild areas on the East Coast. Geller said the wreckage was in “an extremely remote section.” It was reached on foot Friday evening, she said, and a path was bulldozed Saturday to enable recovery efforts.

Police said the pilot was Theodore Bradshaw, 61, of Fort Lauderdale. The others were identified as his wife, Mary Anne Bradshaw, 48; and Charles Rodd, 64, and Diane Rodd, 58, of Palm Beach, Fla. A news account said they were going to a wedding.

Police said the pilot had more than 30 years of flight experience and that the cause of the crash remained under investigation.
