More information is being released in the investigation into the deadly hit-and-run crash that shut down Interstate 70 for hours Saturday night into Sunday.
9NEWS has learned the suspect identified Monday has an Immigrations and Customs Enforcement hold on him; ICE believes 26-year-old Ivan Zamarripa-Castaneda is from Mexico.
Per policy, Denver will not hold him for ICE without a court order if he is able to bond out of jail.
He was arrested Monday morning and held for investigation of vehicular homicide and felony hit and run - at 5 p.m. Tuesday he was still in jail.
Denver Police say Zamarripa-Castaneda was merging his pickup truck onto eastbound I-70 near Brighton Blvd. when he struck a semi-truck. The semi-truck caught fire and the driver of the semi was killed.
