Honolulu Fire Department crews responded to a single- story family home at 98-062 Lokowai St. Sunday morning after being notified that a structure was fully engulfed in flames.

Ten fire units staffed with 35 personnel responded.

Firefighters arrived at 4:13 a.m. and spent 20 minutes bringing the blaze under control. The fire was completely extinguished at 5:38 a.m.
