The children were all found in the finished basement of the home. According to Cpl. Smith, the injured boy was taken by helicopter to Children's Healthcare of Atlanta. There was no word of his condition late Wednesday.

The man was taken to Gwinnett Medical Center for treatment of his injuries. It is not yet clear if the man was the children's father or stepfather.
