Investigators on Friday were trying to determine what started a massive apartment fire in DeKalb County that damaged dozens of units and displaced multiple families.

No one was injured in the blaze at The Marq at Brookhaven, which is just off Buford Highway, DeKalb fire Capt. Eric Jackson said.

But the fire brought down pieces of the roof and a chimney as it burned through the units of the complex. Thirty-six units were impacted by the fire, the American Red Cross said.

Greta Beasley told Channel 2 Action News she got a text at work that her apartment building was up in flames. She said she has renters insurance and is trying to keep cool about the damage.

‘There’s nothing you can do,” she said. “As long as everybody is out and everybody is safe, there’s nothing you can do. There’s no sense in being upset and everything. It’s just not.”

Red Cross volunteers were on the scene Friday afternoon assisting 32 affected families.

“The Red Cross is providing emotional support and help for the families based on their needs for food, clothing and lodging over the next few days,” Red Cross spokeswoman Divina Mims-Puckett said. “Caseworkers will continue to work with the families to help plan next steps, and get them back on their feet.”
