A person who was in custody following a traffic stop was killed Saturday morning when they attempted to flee. The Iowa State Patrol says the incident occurred just after 5-a.m. along I-80 in central Iowa’s Jasper County.

Officials say a State Trooper was conducting an inventory of a van whose driver, 24-year old Enrique Perez, of West Des Moines, was pulled over for suspected Operating a motor vehicle While Intoxicated (OWI). While on the shoulder of I-80 about three-miles west of Newton, an individual in custody ran onto the traveled portion of the road and was struck by a passing vehicle. The impact flung the subject into the median, where they died.

The victims’ name was not immediately released, pending notification of family. The subject was transported to the State Medical Examiner’s Office in Ankeny for autopsy.
