A house fire killed a couple and their four young children early Saturday in a rural area of southwestern Indiana, apparently while the family slept, authorities said.
After firefighters put out most of the blaze, they found the bodies of a man, a woman and three children burned beyond recognition, he said.
The body of a fourth child was found later, said deputy coroner Mark Franklin.
He said it appeared that the victims were overcome by smoke in their sleep and then died as the fire destroyed their one-story, wood-frame home.
The children were preteens, Franklin said, but he did not know their ages or sexes.
The fire's cause had not been determined, but state police said there were no signs of foul play.
The victims' names were being withheld until relatives could be notified.
The home was in an area of woodland interspersed with farms.
