The mayor of Ocean Isle Beach says insurance adjusters are on site at the scene of a burned-out North Carolina beach house where seven college students died.
Mayor Debbie Smith says the town will keep a police officer posted at the house until the insurance company fences off the property.
Smith says town officials still don't know the official cause of death. That information wasn't included by the state medical examiner's office in Chapel Hill when it released their identities.
Smith says town officials were told only that the students died by fire.
A spokeswoman at the medical examiner's office says it could be four to six weeks before lab results are available to pinpoint the causes of death.
Six students from the University of South Carolina and one student from Clemson University died in Sunday's fire.
