The couple's two adult nephews and the girlfriend of one of the nephews also lived at the home at 984 Ala Lehua but were not home when the fire broke out at about 6:10 a.m., said Fire Capt. Emmit Kane.

Kane said the first firefighters to arrive at the scene were told by area residents that two people were still in the burning house.

"An elderly female was found the doorway leading from the parlor to the bedrooms in semi-conscious condition suffering from smoke inhalation," Kane said. "An elderly male was then found in the parlor unconscious and also suffering from smoke inhalation," Kane said.

The two were transported to the Kaiser Permanente Moanalua Medical Center by city paramedics.

Kane said witnesses told firefighters the blaze appeared to have broken out in the carport area and quickly spread to the main building. The fire was reported at 6:12 a.m. and the first firefighters arrived at the home at 6:15 a.m. Eight fire crews consisting of 30 to 35 firefighters eventually fought the two-alarm blaze, Kane said.

"The house is uninhabitable and the Red Cross was called to the scene to assist the family members," Kane said.

A fire investigator said the manner in which the fire spread is consistent with witness reports that it appeared to have broken out in the carport, Kane said.

The cause of the fire and a damage estimate had not yet been determined, Kane said.
