A massive fire destroyed a vacant fourplex in Northeast Bexar County late Wednesday night.
Arson investigators believe it may have been intentionally set.
Firefighters from Windcrest, Kirby, Gardendale and Converse fire departments responded to the blaze in the 7600 block of Oak Chase Boulevard around 10:20 p.m.
Crews said the fire was in full bloom upon arrival and flames were shooting through the roof of the building.
Neighbors were concerned the fast-moving fire would spread to other homes, however firefighters prevented it from spreading.
"The first thing I see when I reached out and opened up my side door is all of the flames coming out of the building," Christopher Barrington said. "It was just chaos."
Neighbors said there have been several fires at vacant apartment buildings in the area in the last couple years, including one in the last few months.
Several of those burned-out buildings have become illegal dumping grounds.
Bexar County recently started demolition on other buildings in the neighborhood, but neighbors are concerned this fire could lead to the next nuisance.
Bexar County officials said the owner will be given an opportunity to clean-up, but the fourplex will also be demolished if the owner doesn't take care of it.
