The Honolulu Fire Department says a fire that left two people dead and one seriously injured in Pauoa last week was accidental. HFD said Wednesday that the blaze was caused by a probable failure of electrical equipment in the first floor laundry room at the home on Booth Road. The fire broke out last week Monday, around 2:20 a.m. A 77-year-old woman and 54-year-old man were found dead in the home. A 77-year-old man was able to escape and was taken to the hospital with burns to his arms and legs, Emergency Medical Services said. The fire caused an estimated $378,000 in damage.
