Two people are dead as a result of a house fire this morning in the 2000 block of Crowe Road in Dacula.

Crews were dispatched to the fire at 8:26 a.m. after a neighbor reported seeing flames coming from the house. By the time firefighters arrived at 8:32 a.m., the single story wood frame house was well-involved.

Gwinnett County Fire and Emergency Services public information officer Capt. Tommy Rutledge said upon arrival firefighters were immediately made aware that two people were still trapped inside the burning house.

The firefighters entered the home and found a 73-year-old male in the living room area of the home. The man was deceased and had burn injuries Rutledge said.

Firefighters also rescued the deceased man's 8-year-old son from a front bedroom. The child was rushed to the hospital with smoke inhalation and heat exposure injuries. Firefighters performed advanced life support measures, but the child was pronounced dead at the hospital.

A 51-year-old woman and a 6-year-old female child were out of the house when crews arrived and were transported to the hospital for evaluation. A bystander helped the woman, who is believed to be the mother of both children, rescue the 6-year-old girl. Rutledge said the mother and bystander pushed out a window air conditioning unit in order to reach the girl.

"Preliminary information indicates that the boy was the only one awake and discovered the fire," Rutledge said in a released statement. "He alerted the parents, and his sister, who were asleep at the time. It is believed that the man was attempting to put the fire out when he died. Fire investigators found no evidence of a working smoke alarm inside the home."

Rutledge said investigators believe the blaze started in the living room/den area, but the exact cause of the fire remains under investigation.
