Official autopsy reports confirm that two of the seven college students killed in an October fire at a beach house in North Carolina died from smoke inhalation and carbon monoxide poisoning.

The Office of the Chief Medical Examiner in Chapel Hill released autopsy reports Friday for 19-year-old Travis Lane Cale and 18-year-old William Robert Rhea.

Reports are pending for the other five victims. At least one additional report was expected later Friday.

The state's chief medical examiner, Doctor John Butts, had previously said he believed all seven students died from carbon monoxide poisoning.
