A Colorado man who prosecutors said went to a former co-worker’s apartment after being fired and instead shot the man’s wife when she answered the door has been sentenced to 42 years in prison in the 2024 killing of 23-year-old Kelsey Roberts-Gariety.
The sentence gives a formal end point to the trial phase of a case that drew attention in Denver because investigators said the killing grew out of a workplace dispute, not a domestic conflict or random attack. A jury convicted Ernest Cunningham of second-degree murder on Dec. 22, 2025, and the Denver District Attorney’s Office announced the 42-year sentence on March 3. Roberts-Gariety’s family said the punishment brought some measure of justice, even as they said the grief of losing her will not end.
The shooting happened June 29, 2024, at Roberts-Gariety’s apartment in southeast Denver near South Dexter Street and East Kentucky Avenue. Prosecutors said Cunningham, then 53, went there intending to confront a former co-worker, Roberts-Gariety’s husband, after losing his job. Instead, Roberts-Gariety came to the door first. Authorities said she was shot there, and Cunningham fled almost immediately. Court records described a fast-moving investigation. One resident in the building heard a gunshot and the sound of someone running. Another captured video of a man leaving in a car. Her husband later told police Cunningham “had issues with him,” and investigators said the video and other surveillance evidence helped officers trace the vehicle and arrest Cunningham within hours.
Authorities have publicly described the motive in narrow terms: anger aimed at Roberts-Gariety’s husband after Cunningham was fired. Reporting based on the arrest affidavit said the husband told police Cunningham used drugs on the job, was terminated, and then began calling and threatening him. Prosecutors have said Cunningham went to the apartment to confront the husband, but no public filing reviewed this week laid out a longer written explanation from Cunningham himself. That leaves some questions unanswered even after conviction, including what he expected to happen when he arrived armed at the building and whether he planned a direct attack on the husband before Roberts-Gariety opened the door. What is clear from the trial outcome is that jurors concluded the killing met the standard for second-degree murder, rejecting any suggestion that the shooting was accidental or legally justified.
Roberts-Gariety was 23 and had built a life in Denver with her husband, Jack Gariety, after moving from Ohio. Her obituary said she was born May 14, 2001, and remained close to family members back in Logan County. In the months after the killing, her sisters described a loss that was both sudden and hard to understand because the violence seemed tied to someone else’s workplace conflict. “Anybody who met her loved her,” her sister Kayla Ratliff said in local television coverage last summer. Another sister, Kylie Al-Nubu’at, recalled the moment the family learned she had been killed and said it felt impossible that “her kindhearted soul was just gone.” Those descriptions helped shape the case in public not only as a homicide prosecution, but as the story of a young woman whose life ended on an ordinary afternoon at home.
The legal path moved more slowly than the shooting itself. Cunningham was charged after the June 2024 killing, and the case remained in the court system for about 18 months before a jury found him guilty on Dec. 22, 2025. Denver District Attorney John Walsh announced the sentence this week and said Roberts-Gariety “would be with us today were it not for Ernest Cunningham.” Walsh said the 42-year prison term ensures Cunningham “will pay a heavy price for his horrific actions.” The district attorney’s office credited Senior Deputy District Attorney Matt James, Associate Deputy District Attorney Makayla Samour and Denver Police Detective Gavin Whitman with helping secure the result. Local reporting has said Cunningham was on parole from a 20-year burglary sentence when Roberts-Gariety was killed, a detail that deepened the family’s anger and sharpened questions about how he had returned to the community before the shooting.
By the time the sentence was announced, Roberts-Gariety’s relatives were measuring justice in different terms than the court. Al-Nubu’at told local television that any punishment above 20 years was “basically a life sentence” for Cunningham, then added that her family is serving “a life sentence of grief.” She also said she believed justice had been served. That reaction captured the split that often follows a homicide case after trial: the criminal case reaches a clear result, but the family’s loss stays open-ended. The apartment building where Roberts-Gariety was shot has long since returned to everyday life, yet the case has remained present for the people closest to her because the facts were so stark. A man came to confront someone else, she answered the door first, and within moments her family’s future changed.
With sentencing complete, Cunningham is headed into the Colorado prison system under a 42-year term, and no new public hearing had been announced as of Thursday. For prosecutors, the case now stands as a finished trial with a final sentence. For Roberts-Gariety’s family, it remains the killing of a 23-year-old woman whose name they are still trying to keep at the center of the record.
