SCOTT CITY ? A house fire in a small western Kansas town has killed a mother and her three children.

Scott City Police Sgt. Andy Newland says the fire started Saturday morning near a radiator heater in the laundry room of a two-bedroom house in Scott City. The cause is under investigation.

The 28-year-old mother called to report the fire. But she was disabled and couldn’t get herself out of the home. The mother, a 4-year-old boy and two girls, ages 6 and 8, were overcome by smoke.

One child died initially, while the mother and two other children were flown to Wichita where they died Saturday afternoon. Newland declined to release the names of the victims.

Scott City is about 30 miles north of Garden City.
