Authorities are still searching for Felix Dino Trujillo, a Denver escapee, who walked out of jail on Sunday night. It is believed that Deputy Matthew Andrews assisted Trujillo is the escape.

The 36-year-old Andrews was arrested Monday at the Denver headquarters on suspicion he helped the fugitive. Sheriff’s officials say Andrews underwent a background check before he was hired.

It is believed that Trujillo was wearing a deputy’s uniform when he walked out of the jail Sunday. Police also believe he has a police radio but they now say he does not have a police firearm.

Trujillo is very dangerous and if seen you should contact authorities, do not attempt to contact him or detain him.
