Crews responding to a vacant house fire on Youngstown's north side early Wednesday found more than just flames.

Firefighters called to the 1400 block of Florencedale Avenue after midnight found the fire had spread through the entire home.

They tell 21 News that gas service had been shut off in September, but the home still had electrical service.

Snapped power lines at the home were sparking, making things tricky for fire crews.

Firefighters also found a woman lying on the sidewalk,

The woman required medical help, but firefighters aren't sure if her injury was related to the fire.

The situation is still under investigation.
