Guam - The Guam Fire Department is leaving the investigation open for the weekend fire at Sunleader Building in Barrigada Heights earlier this month. GFD spokesperson Lt. Ed Artero says the cause of the blaze is undetermined at this time.

It took fire fighters almost three hours to extinguish the fire that caused major damage to a single unit in the building. Artero says GFD is still looking into what sparked the fire.
