Early Friday morning, Chico Police say a woman left her two little girls home alone. Her 8 year old daughter was awoken by the sound of the smoke alarm, and she called out to her mother before evacuating. She found her 9 year old sister sleeping in the car, and the girls ran down the street to a neighbor's home. That neighbor called 911. Police have arrested their mother and charged her with Child Endangerment. We'll have more on this developing story on Action News at 5, 6, and 11.
