The fire, at a single-story house at the corner of Hakaka and Kaimanahila streets, was reported about 10:30 p.m. The blaze gutted the home and caused part of the roof to collapse.

When firefighters arrived, the house was engulfed by fire and one person was unaccounted for, fire officials said.

It was later discovered that a resident of the house was killed in the fire. Officials identified her as Lilly Honda, 82.

Her husband, Takashi Honda, 82, was taken to Straub Hospital, officials said.

It was the 14th fatality in a structure fire on O'ahu this year.
