Driver of Fiery I-70 Crash Sentenced to 10-Years (Zamarripa-Castaneda)

DENVER—Denver District Attorney Beth McCann today announced that Ivan Zamarripa-Castaneda (age 28) was sentenced by Judge Michael J. Vallejos last Friday to serve 10 years in the Department of Corrections.

On March 3, 2018, shortly before midnight, Zamarripa-Castaneda was driving a pickup truck while drunk with a .121 BAC and caused a fiery accident involving a tractor-trailer rig near eastbound I-70 and N. Brighton Boulevard.  That accident resulted in the death of the 57-year-old driver of the semi, John Conrad Anderson.

Zamarripa-Castaneda was subsequently arrested at his home in the 2600 block of W. Bayaud early the next morning.  On March 8, 2019, Zamarripa-Castaneda was charged with one count of vehicular homicide-DUI (F3) and one count of leaving the scene of an accident-death (F3). He pleaded guilty to the first count on July 12, 2019.
