(WSB Radio) A Riverdale couple is dead following a fire at their duplex on Windwood Road.

Clayton County fire officials say, despite the valiant efforts of neighbors, they were unable to save the man and woman.

"We got buckets of water and tried to douse them to kind of give them some relief, but it was too much," one neighbor says.

Neighbors say the heat, smoke and flames were just too much, and kept them from getting close to the building.

"Just couldn't get near it," one neighbor says.  "It was just too much."

Firefighters were able to knock the fire down and discovered the couple inside the unit.

The names of the victims have not been released.

The cause of the fire is not yet known and the investigation is underway.
