LINCOLN, Neb. (AP) — Lincoln authorities say a woman broke a basement window to escape a house fire with her four-month-old baby.

Fire investigator Chuck Schweitzer says an improperly discarded cigarette sparked the Monday afternoon blaze, which started on the home’s front porch. The mother and child were sleeping downstairs when the mother smelled smoke and went upstairs.

Schweitzer says the woman saw heavy smoke and flames on the first floor before returning to the basement. She broke a window, escaped from the home with her child and called 911.

Schweitzer says he found heavy damage inside the home from smoke and flames as well as water damage.
