Ivan Zamarripa-Castaneda, 26, was charged on Thursday with vehicular homicide-DUI and leaving the scene of an accident involving death in this case.

Denver prosecutors believe Zamarripa-Castaneda was driving drunk when he caused the crash on I-70. They say he left the scene and was later arrested at his home.

For days, federal immigrations officials had wanted the city of Denver to notify them if Zamarripa-Castaneda was getting ready to post bond making himself eligible to leave the downtown jail, due to an Immigrations and Customs Enforcement hold on him.

On Sunday, Zamarripa-Castaneda bonded out of jail.

A spokesperson for the Denver Sheriff Department said the jail alerted Immigration and Customs Enforcement an hour after Zamarripa-Castaneda walked out of the jail.

As a consequence, ICE was never able to pick up Zamarripa-Castaneda for possible deportation.

The Denver Sheriff Department has ordered an immediate internal review to try to figure out what happened.
