JACKSONVILLE, FL (WAWS/CNN) - A grandfather in is grieving the loss of his wife and three grandchildren in a fire on Tuesday.
They were at the parents' mobile home when he walked home - a block away - to shower.
Fifteen minutes away from his grandchildren is all it took.
"I heard somebody hollering at the door, hollering, and says your grandbabies are burning up," the grandfather, Clayton Woods, said.
Woods said he was with the four small children all day but walked home to shower around 5:30 p.m.
Only a block away, he ran back to find fire trucks, heavy smoke and flames billowing from his son's mobile home.
Witnesses tried rescuing the family.
"We couldn't get in the front door," Spencer Gwynn said. "I broke out the window on the side, and more smoke poured through."
The family said three children - ages 4, 2 and 10 months - perished in the fire. Their 51-year-old grandmother also died inside. A 6-year-old girl is the lone survivor.
"He's had those babies since they were born, raising them down there, taking care of them," Thelma Carter said.
The grandfather said the children's mom and dad are in jail, and the kids had been staying with he and his wife until Tuesday.
But he said the Department of Children and Families asked that the children be moved back to their parents' home, and that's where they were when the fire broke out.
A 13-year-old boy is being hailed a hero for saving the 6-year-old girl.
The teen saw the fire when he was riding his bike, then went into the house and got the girl.
Firefighters say the fire spread so quickly, it was a miracle the boy was able to rescue anyone from the home.
