Police believe that the vehicle had been traveling eastbound when it left the roadway, hit some trees and went down an embankment where it came to rest near the water treatment plant near the Cedar River.

Investigators determined the vehicle was occupied by an adult male, an adult female, and two children under the age of five. Police believe them to all be family, but there is no further information available at this time due to pending family notification and an official identification from the medical examiner’s office.
