Officials say there were at least four people in the home when the fire began. A man sitting in the porch smelled the smoke and told everyone in the home.

The man tried to make his way to the back bedroom, but there was too much smoke and fire to make entry, officials say.

It is currently unknown how much of a factor about needing a wheelchair played in the woman’s inability to escape the fire. Her identity has not been released.
