It was dark Sunday night, just before 8:30 p.m., when two girls were playing in a pile of leaves near their house near 17th and Main Street.  They were hit by a vehicle.  The 6-year-old girl was killed and her 10-year-old sister was critically injured.  She was flown to a hospital on Life Flight.

The pile of leaves was on the sidewalk and into the street.  Police say it's possible the driver didn't see them and doesn't know what happened.  Police are asking the driver to come forward and talk with investigators.
