A 44-year-old woman is dead following a motor vehicle accident on Interstate-225 after a steel projectile was launched into her SUV, according to the Aurora Police Department.

Police previously believed the accident was caused by a medical emergency, but during the investigation learned that a projectile from an unknown origin entered the drivers window of a Cadillac SUV. 

The projectile struck the sole occupant of the Cadillac and caused the victim to collided into another vehicle, and then the concrete divider barrier.
