MANSFIELD -- A Mansfield woman died early Monday morning in a house fire on the city's north side.
Ninah Stieber, 61, died during the blaze at 612 Johns Ave. She was found by Mansfield firefighters on the stairway to the second floor of the two-story, single-family dwelling.
Richland County Coroner's Office investigator Tom Stortz said smoke inhalation was the likely cause of death, though the victim's body was sent to Montgomery County for an autopsy.
Three other adults successfully fled the blaze and were uninjured, according to the fire department. There were no smoke detectors inside the house, located on the east side of John's Park, firefighters said.
Neighbors called 9-1-1 at 2:33 a.m. to report the structure fire, according to MFD Capt. Dan Crow. Mansfield police were first on the scene and reported a female was upstairs.
Engine 6 was the first fire unit to arrive on the scene, reporting heavy fire venting from the rear of the structure.
"A search of the structure began at the front door while suppressing the fire on the first floor," according to a fire department report. "The stairs to the second floor were located just to the right side of the front door.
"The crew of Rescue 1 was went to the second floor while Engine 6 and Engine 1 personnel continued suppression and search of the first floor. Rescue 1 located the victim on the stairway," the report said.
Firefighters removed the victim from the house and she was declared dead at the scene by the coroner's office.
Crow said 21 firefighters responded to the fire, keeping it from spreading to a nearby house. The scene was cleared at 6:33 a.m.
