Warren Barnes (May 19, 1951 – February 27, 2021)[1] was a 69-year-old homeless man living in Grand Junction, Colorado, United States.

He was murdered and dismembered on February 27, 2021, by Brian Cohee while sleeping near Crosby Avenue below a highway bridge.

On February 3, 2023, he was found guilty of first-degree murder and sentenced to life in prison without the possibility of parole.

The merchants and employees of nearby stores gave him books, occasional pastries, peaches, and drinks.

[12] On March 1, 2021, at approximately 1:48 p.m., a 911 call was made from Cohee's parents to report a decomposing human head and hands found in his bedroom closet.

[7][17] His car was towed out of the water by the police department, and Cohee was allowed to leave the scene without suspicion.

His attorneys argued that he murdered Barnes because he was driven insane by his diagnosed mental health conditions, which included major depressive disorder, autism, and ADHD, as well as environmental stressors.

[23] Later, the judge sentenced Cohee to life in prison without possibility of parole for murder and 13.5 years for evidence tampering charges.

[11] In November 2021, a metal memorial statue for Warren was constructed by Tim Navin near the shop where he used to spend most of his time.
