RIFLE — Authorities remain at a loss to explain why Anthony Green, a 37-year-old Rifle resident, died in the early morning hours of Aug. 22 at the intersection of Railroad Avenue and Third Street.

Neither the Rifle Police Department nor the Garfield County Sheriff’s Office, reached on Friday, could shed any light on the incident.

And the Garfield County Coroner’s office reported that the official cause of death could not be determined by an autopsy.

“It’s still under investigation right now,” said Deputy Coroner Thomas Walton on Friday, explaining that his office is awaiting a toxicology report from the Colorado Bureau of Investigation. That report should be made available within six weeks or less, Walton said.

Green was taken to the Grand River Hospital at shortly after midnight, after Rifle police officers responded to a dispatch report of a man screaming and under some kind of distress at the intersection.

Police reported that Green had suffered minor cuts and scrapes to his face, but no other injuries that they could detect

According to reports, Green screamed for a short time, then fell silent and collapsed, after which he was taken to the hospital by ambulance and pronounced dead at 1:15 a.m.
