CONYERS – Investigators have determined that there were no working smoke detectors in the Conyers house fire that killed four children late Tuesday (Jan. 8).

There was no evidence of smoke detectors found upstairs in the two-bedroom, two-story duplex, authorities said this evening. Both bedrooms are upstairs.

There was one smoke detector found downstairs on the home’s main floor, but there was no battery in it. There also were no sprinklers in the duplex, which at the time of its construction in 1983 were not required, Rockdale County officials said.

The official cause of the fire has not yet been determined and is still under investigation.

There were no injuries to the firefighters and police responding to the incident. Rockdale County Fire and Rescue plan next week to canvas the Pinedale community where the incident occurred, as well as other surrounding communities, to distribute smoke detectors, batteries, pamphlets about the importance of smoke detectors, and other fire safety tips as part of an education and prevention outreach.
