Aurora police are again asking for the public’s help in a December homicide that remains unsolved months later, saying they still have no suspect information in the killing of 53-year-old Matthew Coconis.
According to a news release from the Aurora Police Department, officers and investigators responded to the 14000 block of East Jewell Avenue on Dec. 14, 2025, at about 7 p.m., where Coconis was found dead. The Arapahoe County Coroner’s Office responded to the scene and determined the manner of death to be homicide. The department said the Major Crime Homicide Unit is leading the investigation and that no arrests have been made.
The unit reported that detectives currently have no suspect description to release and are continuing to search for witnesses, tips, and any additional context that could move the case forward.
What Police Are Asking
Investigators are urging anyone with information to contact Metro Denver Crime Stoppers at 720-913-STOP (7867). Tipsters can remain anonymous and may be eligible for a reward of up to $2,000, according to Metro Denver Crime Stoppers.
Police are also asking residents and businesses in the area of East Jewell Avenue to review any surveillance video, doorbell recordings, dash-cam footage or similar records from the night of Dec. 14 and to contact detectives if they spot anything that could be relevant to the case.
Investigation Status
The Major Crime Homicide Unit has described the inquiry as active and ongoing, saying detectives are continuing to work through leads but have not developed suspect information that can be shared publicly at this time. Arapahoe County Coroner personnel responded to the scene and ruled the death a homicide, a finding that keeps the killing under investigative review.
Why Police Are Renewing the Appeal
The renewed outreach on Wednesday is a standard move in longer-running homicide cases, meant to shake loose new tips and jog memories as time passes. Detectives did not indicate whether any new forensic developments prompted the latest appeal, but emphasized that even small pieces of information can help build a clearer picture of what happened to Coconis on East Jewell Avenue that night.
