An illegal alien has been charged with murdering an American in Denver just one month after being released from jail.

Ever Valles is a criminal illegal immigrant who is one of two men to be charged in the killing of 32-year-old Tim Cruz, a Hispanic-American landscaper, at a Denver light rail station.

Valles and his accomplice Nathan Valdez allegedly attempted to rob the victim and then murdered him while he was waiting at the station, according to Fox 31 Denver.

The illegal alien was previously arrested in October by Denver Police for car theft and other charges.

After the arrest, federal Immigration and Customs Enforcement officials asked the Denver Police Department to notify them when Valles was going to be released because he was wanted for possible deportation.

After he posted bond, Denver Police proceeded to release the illegal alien suspect without notifying the ICE officials in time.

NBC 9News reports:

A statement from ICE sent to 9Wants to Know says ICE believes Denver failed to honor a detainer it placed on Valles upon his initial arrest in October on the car theft case. ICE Detainers, in essence, seek a heads-up from a jail when a person living in the country illegally is expected to leave the facility.

According to ICE, Ever Valles was a priority individual because he was a known gang member and an illegal alien, yet Denver Police decided to ignore the pleas from the immigration officials, allowing him to roam free.

From Breitbart:

DPD officials insist that ICE was notified, but reporters were told by ICE that the police only gave them a 25-minute warning before Valles was released. Immigration officers did not have time to get to the station to pick Valles up and take him into federal custody.

A Denver Sheriff’s spokesman insisted that their job is not to “hold people on civil matters.”

The City of Denver has not openly declared itself a “sanctuary city,” but its policies are little different from cities that have made that bold statement.

The news site notes, “only weeks ago Denver Mayor Michael Hancock said he ‘welcomes’ being considered a place of sanctuary for illegals even if his city hasn’t made the official declaration.”
