A woman was killed in a fire at a home in Philadelphia's Ogontz neighborhood early Thursday morning, officials said.

Crews were called to the home on the 6200 block of Ogontz Avenue, near Limekiln Pike, around 4:45 a.m. 

Firefighters went into the home and fought heavy flames as they worked to get the woman out, Assistant Chief Gerald Boyle said at the scene.

"The fire was raging on the first floor when they went in with hose lines to extinguish it and separate her from the fire," Boyle said.

The woman was found unresponsive on the first floor and then pronounced dead on the scene. Authorities believe she is about 60 years old, but are still working to identify her.

A neighbor said the home is occupied by a woman who lives alone.

"I did see flames once they made it into the house. I saw flames actually downstairs, and I just knew it wasn't going to be good," neighbor Jerry Adams said.

The woman was the only person inside the home, Boyle said.

Firefighters also battled partial collapses within the home, which made it more difficult to get inside. There was some slight damage to a home next door.

Boyle said the blaze was brought under control in about 40 minutes. The cause is still under investigation.

Members of The Salvation Army are on the scene. The 6200 block of Ogontz Avenue remains closed for this investigation.
