Guam - Once the smoke clears, the Guam Fire Department will launch an investigation into what caused the fire that erupted inside the National Office Supply building in Barrigada. According to GFD Spokesperson Joey San Nicolas, a 911 call came in just after 5:45 this morning. An engine unit and medic were on the scene a few minutes later.
