HOUSTON -

A man died Thursday after a house fire in southeast Houston.

Firefighters arrived at the home on Heron and Southbank Drive at 12:50 a.m. Friday. They saw flames shooting from the front of the home.

After going inside, they found a couple in their 60s. Both were rescued, but suffered smoke inhalation and were taken to the hospital.

Crews went back in the home for a more intensive search and found Michael Baker, 37, badly burned and suffering from smoke inhalation. He died a short time later at the hospital.

"They had to be make an aggressive attack. It got so hot and the fire got so aggressive," said Capt. Lozano with the Houston Fire Department.

Fire investigators are looking for a possible cause.

"I snuck around the side of the house and saw a big old gaping hole in the back of the house," said Oland Baker Jr., Oland Baker's son. "It's hard because we just lost my mom six years ago. I'm definitely not friendly with death, but I'm trying to maintain, keep my faith. I'll be OK. We'll be OK."

Michael Baker was staying in his father's house.

Family members said there were oxygen tanks in the home, but it is uncertain if those tanks played a role in the fire.

Investigators said someone may have been smoking inside the home. Neighbors reported hearing two explosions.
