Prior to that, on Aug. 4, firefighters were called to a fire at an occupied apartment complex in the 300 block of 32nd Street that displaced 13 residents. The night before that, an under-construction townhome complex sustained an estimated $1.6 million in damages following a fire.

While a firefighter was treated for heat exhaustion following the second fire, no further injuries have been reported as a result of the fires.

According to Ogden Fire Chief Mike Slater, these investigations are all ongoing with the focus being on Saturday’s blaze.

“We’ve kind of diverted focus while we have the ATF (Bureau of Alcohol, Tobacco, Firearms and Explosives) here and we’re working alongside them,” he said. “They’re still in the pending mode because of this big fire.”

On Wednesday, the ATF sent out a press release about its National Response Team coming to Ogden to assist in the investigation of Saturday’s fire.

“On August 8, the Ogden Fire Department arrived to find the building heavily involved in fire,” the release said. “The blaze burned for several hours and destroyed the structure. After consulting with other local agencies, the Ogden Fire Department requested the National Response Team to assist with the investigation of the origin and cause of the fire.”

“When our National Response Team arrives on scene, it represents more than just federal support,” ATF Special Agent in Charge Brent Beavers said in the release. “It’s ATF’s commitment to strengthen and support our local public safety partners in large-scale investigations by bringing specialized resources, expertise and coordination when it’s needed most.”

No further information has been released on that fire.

Slater said it isn’t clear whether there are links between any of the three fires.

“In the preliminary investigation on the 32nd Street fire, there’s no similarities to that fire in the other two apartment fires,” he said. “The two apartment fires — they were in such different stages of construction. We’re still investigating all of those.”

He said the Ogden City Fire Department has been reaching out to other construction sites around the city.

“We’re reaching out to construction companies at sites around the city to talk about protection of their construction sites,” he said. “That’s really our focus right now as a fire department — to prevent this from ever happening again. We’re working with the homebuilders and construction companies and these apartment builders to make sure that we have a plan in place to secure these buildings and make sure it doesn’t happen again.”
