The woman also had a daughter who lived with her. The daughter was critically injured in the blaze.
The fire broke out just after 7:30 p.m. on Wednesday. Firefighters say it took them about an hour to put the fire out.
The cause of the fire is under investigation. Neighbors say the woman had a lot of stuff in her home. One neighbor described her as a packrat. That neighbor saw the fire from across the street and tried to help the victim.
"The smoke was so thick and we tried to break the window, the door ... and it was so cluttered in the house that we can't even get in," said Uthai Thiranop, a neighbor. "I told the guy that I lived here and I know the floor plan of the house. And we go in through the window and I used a brick and break the window, and try to get her out. But we can't see anything."
"The daughter said the mom is still inside," added Thiranop. "And we know that there is only two that live in the house."
Fire officials confirm there was a lot of stuff inside the home. They say the items, along with the heat, likely fueled the blaze.
