Rapid City Police are investigating the circumstances surrounding the death of a 18-year old woman.
The investigation started with a report of a woman who collapsed early yesterday morning on the 4200 block of Starlite Drive.
A man said the teen had fallen out of a vehicle. When the victim was brought to the hospital, authorities say they discovered her injuries were consistent with being run over by a vehicle. She has since died in the hospital.
Authorities hope to release additional information later today.
