SUSPECT ARRESTED IN DENVER'S 40th AVE. HALLOWEEN MASK KILLING

A man suspected of being the 40th Avenue Halloween mask killer has been arrested, Denver police announced Monday.

They identified the suspect as Deontre Yorks, 23. The slaying occurred in the early hours of Halloween in a parking lot in the 3200-block of East 40th. The victim, a man age 46, was pronounced at hospital. "Investigators processed the scene and collected several pieces of evidence, including shell casings, a Halloween mask worn by the suspect, and surveillance video," police said. "Through extensive investigative efforts by DPD’s Homicide Unit, crime analysts and the Denver Crime Lab, investigators identified Deontre Yorks as the suspect," police said.

"At this stage of the investigation, it appears Yorks and the victim were involved in an altercation that escalated to Yorks allegedly shooting the victim," police said. "The victim then fired back at Yorks, striking Yorks in the shoulder." Yorks, who sought treatment at a hospital, was arrested on Nov. 6 in Colorado Springs and is being held for investigation of first-degree murder, police said.
