"As my deputies arrived, we learned that there were four individuals in the home," said Sheriff Wayne McKinney, "at least one individual was bound by a wheelchair, a 69-year-old male."
That man was identified by family members as Henry Bernard.
They said he was a former volunteer fire fighter and retired preacher who loved nothing more than to preach, pray, and fish.
"These people are well known," said Duncan Fire Department's Assistant Chief Kevin Hammack, "They've got family members that have been firefighters. It just kind of touches us all."
Officials said a woman, who was identified by family members as Henry's wife Bernice, and two girls were also in the house when the blaze broke out.
The girls made it out, and that's when family members said Henry's son, David, and grandson, Craig, ran back into the burning structure.
Despite severe burns to their feet, the men pulled Bernice from the flames.
But Henry, who was in a wheelchair, couldn't be saved.
Hours after fire crews left the scene, the piles of ash and rubble continued to smolder. Proof of just how hot the blaze really was.
Officials said it makes makes it just that much more heroic that two men went back inside the house to rescue their family members.
"I believe that's a heroic act," said Assistant Chief Kevin Hammack, "to put yourself in danger, try to save somebody else."
Heroism which the family, and this area, won't soon forget.
