HOUSTON - Investigators say a Houston day care operator left the children she was caring for alone, while a stove top burner was on, before a fire at the home that killed four children.

An arrest affidavit made public Monday says 22-year-old Jessica Tata left the children without adult supervision before the fire began. Investigators believe the burner was the source of the fire that also injured three other children.

Tata has been charged with reckless injury to a child involving serious bodily injury. She had not been arrested by early Monday afternoon.

Attempts by The Associated Press to contact Tata in person or by phone at multiple addresses and telephone listings have been unsuccessful. Two of the injured kids remain hospitalized in critical but stable condition.
