A 61-year-old woman was arrested Friday after “intentionally” setting fire to two Gwinnett County homes, authorities said.

Within a span of around 20 minutes, Hong Huynh is accused of igniting homes about three miles apart. The Norcross woman is facing charges of first-degree arson, aggravated assault, aggravated battery, use of a destructive device and possession of tools for the commission of a crime, court records show.

On June 1 around 5:45 a.m., a 911 caller reported that her neighbor’s garage was ablaze. Within minutes, firefighters arrived at the two-story home in the 6000 block of Buckingham Court and located a victim. A man who lived there was taken to a hospital with serious injuries sustained during the blaze, officials said.

The fire was extinguished at 6:13 a.m., and by that time, crews had already been called to another house fire in the 1300 block of Turners Ridge Drive.

That fire was reported at 6:04 a.m. by one of the residents, who told dispatchers the flames were spreading to a vehicle in her driveway. Officials said they confirmed the fire appeared to have started in the exterior of the two-story home.

The blaze was extinguished by 6:20 a.m. One person sustained injuries not considered life-threatening.

Ten people were displaced, including two children, between the two fires.

Investigators said they determined both fires were “set intentionally and were connected,” but did not explain why the homes were targeted.

Anyone with information on the fires is asked to contact Gwinnett investigators at 678-518-4890 or the Georgia Arson Control Hotline at 800-282-5804.
