Investigators believe the fire was accidental and that it started on a deck, said Mayor Debbie Smith of Ocean Isle Beach.
Though students heard through word of mouth which students survived, the names of the victims had not been officially announced. At the university's Greek village yesterday morning, a garnet and black banner with the school's mascot, a gamecock, flew at half-staff alongside an American flag outside a fraternity house. Two black ribbons were wrapped around the columns of another house.
Kaitlynn Forsyth, 20, a junior and marketing major, said she learned about the fire while studying in the library Sunday night, and quickly went to the Internet to find out more.
"I seriously just sat there. It took everything not to cry," she said. "The more we looked at stuff, my heart just sank. I had to go back to studying to fight off my tears. I just imagine it could have been anybody."
The students had gathered at the house for the weekend to enjoy the fleeting beach weather. All that was left of the structure yesterday was a charred shell. A burned-out car sat in the driveway, cordoned off with police tape.
The fire struck before 7 a.m. and burned completely through the first and second floors, leaving only part of the frame standing. The waterfront house - named Changing Channels - was built on stilts, forcing firefighters to climb a ladder onto the house's deck to reach the first floor.
One witness described seeing three students sitting on the ground screaming as the house burned, and another person jumping from a window into a waterway. Others said the heat was so intense the front door was too hot to open, preventing rescue attempts.
The mayor said investigators told her the fire started on a deck facing a canal on the west side of the charred house. That side of the building appeared to have had the most damage. She said investigators gave no indication of a possible cause.
"They may not be able to determine what started it," Smith said.
She said it could be a couple of days before officials release victims' names. None of the bodies had been positively identified, she said.
The burned house sits on one of a series of peninsulas, all tightly packed with homes, that connect by canals.
Several houses near the burned one were filled with college students.
