(WSB-TV) --- Local, state and federal fire investigators said it could take days before they can determine what started a deadly Rockdale County blaze that killed four children.
The fire started around 11 p.m. Tuesday at the Pinedale Circle home.
Investigators said when she was alerted to the fire, Reba Glass threw her 6-year-old son, Darnell Jr., out a second-story window then jumped out herself.
She then ran back inside and rescued her mother asleep downstairs.
But when she ran back upstairs to save the other four children, the flames caused second- and third-degree burns over 40 percent of her body.
Ah'Dariya, 9, DeShawn, 7, Amoni, 3, and 8-month old Deon, Jr. all perished in the inferno.
As the fire burned, LaMonte Stroud was arriving home from a Rockdale High School wrestling match.
Still wearing his wrestling uniform, Stroud tried to rescue the children. He said he saw Ah'Dariya in an upstairs window crying for help.
"I heard somebody just yelling and screaming," he said. "She was just saying, 'Help me, help me.'"
Unable to get up the stairs, Stroud said he rushed around back and climbed up to a second-story bathroom window.
"I started hitting the window with my fist," Stroud said. "I broke the window, and I was screaming 'Come to the bathroom, come to the bathroom, I can get y'all out.' But I guess they couldn't get out of the room or they were already gone by then."
Conyers Police Sgt. Bill Connell was the first officer on the scene. He attempted to get up the stairs using a fire extinguisher, but the inferno was just too intense.
"I tried to knock
(the fire) down with a fire extinguisher to make it through," Connell said. "I could feel it burning the top of my head. It's incredibly frustrating. You're looking for anything you can do, and there's just nothing."
Connell spotted Stroud and together they tried to use a stick to knock out the remaining
upstairs windows hoping they would see the children's faces, but they never did.
Investigators said they found all four bodies in two rooms either in bed or next to one.
