There’s a documentary that’s leaving even the most hardened fans unable to sleep.

Released in March 2024, the 105-minute long video released to true crime channel Explore With Us – and available to stream free on – explores the Brian Cohee case.

Brian was still a teenager, just 19, when he 69-year-old Warren Barnes. Warren was homeless and sleeping on the streets in Colorado in 2021, when Brian killed and dismembered him.

In horrific footage included in the documentary, his mum revealed she found a human head and human hands in her son’s closet and called the police to alert them to what had happened. She broke down as soon as cops arrived, falling to her knees in tears.

More shocking footage shows the moment Brian casually confessed to his crimes when confronted by cops.

One officer asked: “Your parents have raised concerns about some items they may have found in your room. Can you elaborate?” and Brian responded: “Yes, I believe so. A human head and hands, from that man who went missing. I killed him with a knife.”

As for why he did it? Brian confessed: “I always wondered what it would feel like to commit murder.”

Cohee was arrested after attempting to dispose the rest of the body parts by hiding them in the trunk of his car and attempting to drive the vehicle into the Colorado River.

The documentary explores how Brian killed Warren Barnes, confessing he made “animalistic noises” while he stabbed him. Eventually he was sentenced to life imprisonment without the possibility of parole after being found guilty of first-degree murder.

He was also convicted on two counts of tampering with a dead body and tampering with evidence. Though he pleaded insanity in court, Judge Richard Gurley wasn’t merciful as he described the case as “one of the most horrific” he’d ever encountered.
