Five family members -- including four children ages 5 and under -- died in an overnight house fire in Newnan, Georgia, authorities said Saturday. The house was engulfed in flames when firefighters arrived at the scene, Police Chief Douglas L. Meadows said. The cause of the fire is under investigation. One girl, around 10 years old, escaped, with the help of a passerby, the police chief said. She was taken to the hospital but is expected to be fine, he said.
