AKRON, Ohio -- A mother and three children died in a house fire Wednesday morning in Akron’s Kenmore neighborhood.

Firefighters responded just after 9 a.m. for a call about a fire that broke out at a home on 18th Street SW near Battles Avenue, according to an Akron Fire Department spokeswoman. They tried to enter the home but were forced out by the severity of the fire.

A 28-year-old man living in the home made it out, the spokeswoman said. His fiancé, about 30 years old, and her three children, ages 5, 7, and 10, died in the fire, according to the spokeswoman.

The fire was reported under control just after 1 p.m.

The instability of the home, the extensive damage caused by the fire and sub-zero temperatures hindered crews and investigators, the spokeswoman said.

The fire’s cause remains under investigation.
