Investigators are trying to figure out what caused a Honomu home to go up in flames overnight. Fire officials say neighbors reported the blaze around 3 o’clock Saturday morning. When firefighters got there, they said most of the structure collapsed, and the house was fully engulfed in flames. They were not able to find anyone inside the home. The flames were deemed under control just after 4 a.m. Damage was estimated $194,000. The investigation is ongoing.
