Neighbors say that around 8pm Thursday, they heard a loud pop then saw all the fire trucks. When firefighters made their way inside they found the man lying in the family room, near his fireplace.
"They began performing CPR. He was taken to Memorial Herman Hospital where he has burns over 80 percent of his body. He is in critical condition," said the Houston Fire Department PIO, Patrick Trahan.
Paramedics were giving him CPR en route to Memorial Hermann Hospital, where he is listed in critical condition. The victim was the only person inside the home and is believed to have lived alone.
Not much damage could be seen from the front of the house, but damage was visible in the back.
Firefighters suspect the fire started in the kitchen, possibly on the stove, but arson investigators are still trying to determine the official cause of the blaze.
