Crews were dispatched at about 12:35 a.m. to the 6600 block of Singleton Lane, where they arrived to find the eight-unit structure engulfed in flames.

A man was found dead at the scene. A woman who suffered moderate injuries and a man with minor injuries were transported to a hospital for treatment. Their names and conditions were not immediately released.

After firefighters brought the blaze under control, the building collapsed. The cause of the fire remains under investigation, and authorities have not said whether they suspect anything suspicious.

The early-morning timing of the fire — when most residents would have been asleep — raises familiar concerns about fire safety in older multi-family housing. Condominium and apartment buildings can present particular challenges for residents and responders alike, from shared walls and common attics that allow flames to spread quickly to limited exit routes.

Fire officials have not released additional details about how the fire started or whether working smoke alarms were present in the building. It was not immediately clear how many residents were displaced by the collapse or whether any units were occupied at the time crews arrived.

Neighbors in the surrounding community, a residential area of DeKalb County, were left shaken by the loss of life and the destruction of the building. The Red Cross and local assistance organizations were expected to help those displaced.

Anyone with information about the fire is asked to contact DeKalb County Fire Rescue as investigators continue to piece together what happened. This story will be updated as more information becomes available.
