Imperial Grove Fire: Two firefighters being treated

What we know:

Officials said the fire sparked up in the 5500 block of Imperial Grove on Thursday afternoon. 

The Houston Fire Department said there were three people from the home. Two were not home at the time and one person is unaccounted for. 

Authorities said two firefighters are being treated due to the fire: one for a heat-related issue and the other for smoke inhalation. 

A neighbor told FOX 26 they they heard a loud explosion and feeling the ground shake. They also said the fire was worsened by wind gusts.

Officials later said the missing person is a 20-year-old woman, and family was uncertain whether she was home at the time of the fire.

What they're saying:

Arthur Chambers, who lives nearby, described the moment the father of the missing woman arrived and tried to enter the burning home.

"The dad finally got here about 40 minutes into it and tried to fight his way in to get his baby," Chambers said. "I don’t blame him. I would’ve fought my way in to get my baby too."

What we don't know:

It's unclear how the fire started as it's under investigation. 

What's next:

The Harris County Fire Marshals Office and fire crews will be working through the night to go through the home piece by piece in the search of the adult female that is unaccounted for. 

Officials said the two-story home did collapse, which means crews are sifting through two stories of debris with each room they search.
