Mauricio B. Baires, a 20-year-old white male, was killed by gunfire in Aurora, Colorado, on April 5, 2003. That day, Aurora police officers were dispatched to 12085 East Colfax Avenue after reports of shots fired rang out along the busy corridor. When they arrived, witnesses told them that two vehicles had been involved in the confrontation and had already sped away from the scene, leaving behind only the echo of the gunshots and scattered fragments of what had just happened.
A short time later, officers searching the surrounding area found Baires in the alley running through the 1200 block between Newark and Nome Streets, not far from where the shots had been reported. He had suffered a gunshot wound to the head, and despite the efforts of responders, his injuries were fatal. The discovery turned what began as a “shots fired” call into a homicide investigation and fixed that narrow alleyway as the central scene of the crime. Official records would later summarize the case starkly: Baires was lost to gun violence in Aurora on that date, his life ended at just twenty years of age.
In the early stages of the investigation, witnesses provided a description of the gunman that investigators hoped would break the case open. The suspect was described as a Black male with a light complexion, wearing a white T-shirt, his hair in braids, and sporting a thin mustache with a goatee and/or beard. Detectives also had the critical detail that two vehicles were seen fleeing the area immediately after the shots were fired, suggesting that the shooter might not have been alone and that others could have information about what happened that day. These details formed the backbone of public appeals, as investigators tried to reconstruct the movements of those vehicles and the man described by witnesses.
Despite those leads, no clear breakthrough followed. Over the years, law enforcement and community partners repeatedly renewed their appeals, emphasizing that the suspect or suspects responsible for the killing had still not been identified. Metro Denver Crime Stoppers and the Aurora Police Department have continued to publicize the case, explicitly noting that the individuals behind Baires’s death remain unknown and urging anyone with information to come forward in hopes of finally providing answers in the unsolved homicide. Public records and official cold case summaries reflect that there have been no publicly reported arrests in connection with the shooting, and no suspect has been named, leaving the case open and unresolved decades after the night that Baires was killed in that Aurora alleyway.
