A tragic incident unfolded in Colorado when a disgruntled worker took the life of his former boss’s wife after being fired from his job while on parole. Ernest Cunningham, 53, was handed a 42-year prison sentence for the murder of Kelsey Roberts-Gariety in June 2024, as reported by Denver District Attorney John Walsh.
Walsh emphasized that Kelsey Roberts was a young woman full of promise, whose life was cut short by Cunningham’s senseless act. The sentencing was a step towards ensuring that Cunningham faced the consequences of his heinous actions.
Prior to the murder, Cunningham was on parole from a 20-year burglary sentence and was employed by Roberts-Gariety’s husband. However, his employment was terminated by Jack following allegations of drug use at work, as detailed in an arrest affidavit obtained by the Denver Post.
Enraged by his dismissal, Cunningham began making threats to Jack and had even shown up uninvited at their residence. On the fatal night, he went to confront Jack but ended up fatally shooting Roberts-Gariety when she answered the door, leading to her tragic demise.
In the aftermath of the incident, Jack Gariety informed the authorities that Cunningham had ongoing issues with him and knew their residential address. Surveillance footage also captured Cunningham’s car leaving the scene shortly after the shooting, adding to the evidence against him.
Despite Cunningham’s troubled history, which included failed drug tests and missed assessments, a parole officer had deemed him as “low risk” just two months prior to the murder. This revelation prompted the Colorado Department of Corrections to acknowledge deficiencies in their screening process for dangerous offenders.
Reflecting on her sister’s untimely death, Kylie Al-Nubu’at expressed a belief that if Cunningham had not been released, her sister might still be alive today. The pain of losing her sister, who was one of nine siblings, on her birthday continues to weigh heavily on their family.
However, the substantial prison sentence handed to Cunningham brought a sense of closure to Al-Nubu’at and her family. She viewed the lengthy term as a form of justice served for her sister’s life taken abruptly by Cunningham’s actions.
As they navigate the enduring grief of their loss, the family finds solace in the accountability meted out to Cunningham through the legal system. The sentence, exceeding 20 years, effectively equates to a life sentence for Cunningham, bringing a semblance of peace to a family grappling with the aftermath of a senseless tragedy.
