An ICU nurse from Colorado has been accused of sexually assaulting unconscious patients who were supposed to be in his care. The nurse allegedly sexually abused the victims and recorded the alleged sex crimes. The male nurse labeled the sex assault videos as his own "Dexter Collection," according to police.

Christopher Peter Lambros, 61, was arrested last week for allegedly sexually assaulting victims who were unable to consent.

Lambros — a nurse with the intensive care unit at St. Mary’s Medical Center in Grand Junction — reportedly recorded himself performing lewd, sexual acts on patients who were unconscious. He is also accused of snapping selfie photos of a sexual nature with patients in compromised situations.

Around 8:45 p.m. on July 9, a colleague contacted 911 to report that they had witnessed Lambros "taking photos of a patient’s genitals" at St. Mary’s Hospital, according to a probable cause affidavit.

The colleague alleged to have seen a sex crime when she went to check on a patient. The lights in the hospital room were reportedly turned off and the curtains were drawn around the bed.

"When she pulled back the curtain she saw the patient, who was unconscious, with her gown pulled up, exposing her breasts, and the bed sheet was pulled down, exposing the patient’s genitals," the affidavit states. "[The witness] said she saw a nurse, who she knew as Chris Lambros, with his head on the patient’s stomach, with his face toward the patient’s feet, with what she believed [was] his right arm extended, holding what she was sure was an unknown make/model cell phone in a black case, in a position as if he was taking a 'selfie’ picture."

The New York Post reported, "When the woman opened the curtain, she said, she discovered the patient lying unconscious with her hospital gown pulled up to reveal her breasts, and the bed cover pulled down showing her genitals."

The complaint stated that the witness saw Lambros with his head resting on the patient’s stomach with a phone in his hand in a position suggesting he was photographing a selfie.

Lambros was allegedly startled and dropped his phone. He then covered up the naked patient.

When interviewed, Lambros told investigators that he was giving the patient an injection in the stomach area to prevent blood clots.

However, investigators say that there was incriminating evidence on Lambros' cellphone.

The Daily Beast reported, "After obtaining a search warrant, a digital forensic analysis of the phone found 'photographs and videos of Lambros posing with a number of victims who were unconscious, in the hospital setting,' the affidavit said. 'Lambros was photographing himself sucking on victims’ breasts and digitally penetrating victims,' the document states."

The outlet added, "The digital forensic analysis also found that 168 photos and videos had been deleted from the phone between April 30 and July 9, the latter date being the day that Lambros was reported for the alleged selfie incident."

In a video allegedly recorded in June, Lambros can be heard whispering to the camera, "Don’t ever get rid of these videos,” and “You need to keep them forever… this is your Dexter collection,” the affidavit states.

The reference is likely a mention of the fictional serial killer Dexter Morgan in the TV show "Dexter."

Lambros was booked into the Mesa County jail on $250,000 bond.

President of St. Mary’s Medical Center Bryan Johnson said, "What this former nurse is accused of is reprehensible and goes against everything we believe and value at St. Mary’s Medical Center. Patients put their trust in us and should feel safe in our care.”
