Officials say child ignited Christmas tree that sparked Fairmount fire

Details: Three adults and nine children died of smoke inhalation, according to the city's Medical Examiner's Office.

• Officials originally said eight children died in the blaze.
• The 5-year-old was one of two survivors from the second unit, where the blaze was located inside the three-story building, Thiel said. The other escaped out of a window, he added.

The Medical Examiner's Office identified the following as victims killed in the fire:

• Dekwan Robinson, Destiny McDonald, Janiyah Roberts, J'Kwan Robinson, Natasha Wayne, Quientien Tate-McDonald, Quinsha White, Rosalee McDonald, Shaniece Wayne, Taniesha Robinson, Tiffany Robinson and Virginia Thomas.

Of note: 14 people were in the second unit at the time of the fire, and eight in the first unit, Thiel said. Officials initially said 26 people were inside the building.

• The second unit had seven battery-operated smoke alarms — six of which were disabled, Thiel said.

What they're saying: "I believe in our ability to create an environment where you don't have to have 20 or 30 people living in one apartment," City Council President Darrell Clarke said, citing the city's lack of affordable housing as an underlying issue.

What's next: Authorities will issue a final report when the investigation is completed, which could take months, Thiel said.
