A late-night fire ripped through a South Side duplex on Tuesday, leaving the Theo Avenue property badly damaged but, against the odds, all residents made it out without injuries. Flames tore through living spaces and up into the roofline, leaving the two-unit building unstable and largely uninhabitable. The San Antonio Fire Department has called in its arson team to figure out how the blaze started.
What crews found
Firefighters arriving around 9:20 p.m. found heavy flames and a tricky layout that made the blaze tough to battle. At one point, the fire pushed into the attic and caused part of the roof to collapse. The department reports the duplex suffered severe damage and confirms that everyone inside escaped safely with no reported injuries. As reported by KSAT, arson investigators are on scene examining how the fire started and spread.
Theo Avenue has seen recent blazes
Neighbors and local coverage note that this is not the first fire along the Theo Avenue corridor in recent years, a pattern that leaves older housing stock especially vulnerable. Hoodline previously covered a heavy attic fire on a nearby block that caused tens of thousands of dollars in damage, heightening concerns for residents along the stretch.
