ADA, Okla. (KTEN) — Firefighters worked Wednesday morning to control a fire that spread to multiple buildings in downtown Ada.

"I was down the block standing in line when I saw the first puff of smoke," said Jamie Young Marshall in a Facebook post. "Then in like 60 seconds, it went 'woosh.'"

"It's definitely intense, but it's unreal," said witness Matthew Smith. "You see it on the news all the time, but when it's close to home, it's different."

Ada Fire Chief Rob Johnson said the call came in just before 9 a.m., and the first units arrived within minutes.

He said the fire broke out at the Salvation Army Family Store Donation Center at 305 East Main Street.

Firefighters said a large fire in downtown Ada on June 5, 2024 started at this Salvation Army donation center.

"We tried an interior attack," the chief said. "The conditions of the building and the fire load had us back out, so we started an exterior with our ladder truck... basically a battle within the roof area of the structure."

Ada fire crews — along with Pontotoc County volunteer fire departments — were working to douse the flames at the Salvation Army center when the flames spread to a vacant building next door that was built in the year 1920.

Fire spread to multiple buildings in downtown Ada on June 5, 2024.

As of 12:30 p.m., Johnson said the flames were under control, but the fire had not yet been extinguished.

"It's been years since we had one downtown like this," he said. "This was an area that we have been concerned about because the building was vacant, the Pre-Paid Legal building was vacant with furnishings, so we're playing catch up."

The state fire marshal will determine the cause of the fire.

"It's a horrible, horrible thing," said Ada City Council member Don Griffith. "If I'm guessing correctly,  they're getting ready and will probably have to bulldoze both of those buildings down. It's going to be a huge undertaking."

No injuries were reported.

A fire in downtown Ada on June 5, 2024 appeared to gut this vacant building that dates back more than a century.
