DENVER (KDVR) — Parts of Larkspur near Fox Farm and Spruce Mountain were under a shelter-in-place Friday while police searched for an escaped inmate.

According to the Douglas County Sheriff’s Office, the county’s SWAT team was in the area looking for Luis Fernando Certa-Regaldo. Investigators remained there Friday night, but they had not found him “after an exhaustive search.”

The sheriff’s office said he is considered armed and dangerous.

Certa-Regaldo was arrested Wednesday in Weld County on suspicion of possession of a stolen vehicle, obstruction and attempting to influence law enforcement.

While in custody, he was taken to the Northern Colorado Medical Center in Greeley for medical clearance before being booked into the county jail.

Around 7:30 p.m. Wednesday, Certa-Regaldo escaped from the hospital on foot.

Certa-Regaldo is a white 27-year-old man, around 5 feet 10 inches tall and weighing 200 pounds. He has brown eyes and when he was in custody he had black hair and a short beard. He also has a tattoo on his right arm, the sheriff’s office said in a release about his escape.

He was wearing a white T-shirt, dark pants and white shoes with a blue stripe when he escaped. An updated description from the sheriff’s office Friday afternoon said he was last seen wearing black pants, a black shirt with cutoff sleeves and a black baseball cap.
