Angela R. Quintero Olejniczak was a 49-year-old white woman living in the small community of Fort Mohave, Arizona, where she was known as a kind, bubbly presence who loved helping others and cheering for her beloved Denver Broncos. Friends and family memorialized her online as “very sweet and loving,” a deeply caring mother with a warm smile who brightened workplaces such as local retail stores and resorts along the Colorado River.
She had survived cancer and, according to her mother, worked at a cancer center, making her loss especially painful for those who knew her both personally and through her work in the community.
On the night of June 23, 2020, Angela was at the home she shared with her husband, Keven Scott Olejniczak, on East Gran Circulo in Fort Mohave. What began as an argument inside the house turned into what prosecutors later described as an alcohol-fueled confrontation. Keven was said to be heavily intoxicated, and during the dispute a 9mm semiautomatic handgun came into play. According to the account summarized in court, Keven claimed that Angela approached him with a baseball bat and that the gun went off during a struggle, but investigators and the victim’s family rejected this version of events. When Mohave County sheriff’s deputies arrived around 11 p.m., they found Angela’s body hunched over in a bedroom; she had been shot multiple times, including numerous wounds to the head.
Keven was arrested at the scene and ultimately charged in connection with Angela’s killing. In April 2021, he pleaded guilty to second-degree murder by domestic violence for her shooting death, formally acknowledging his role in what the state had characterized as a lethal pattern of abuse that culminated in the shooting. At sentencing in Kingman, Arizona, his defense attorney asked the court for the minimum term allowed under the plea agreement, citing Keven’s age, mental-health issues, lack of recent serious convictions, claimed struggles with bipolar disorder and alcoholism, and letters of support from community members. Keven himself expressed regret, saying he should have left the house that night and insisting that his wife was his best friend, while maintaining that the shooting was accidental and occurred during a struggle over the gun.
The prosecution and Angela’s loved ones painted a starkly different picture. Family and friends described Keven as manipulative, possessive, and verbally abusive, alleging that he had isolated Angela from others and exerted controlling behavior over her. Her mother strongly disputed any suggestion that Angela had attacked her husband, stressing instead her daughter’s gentle nature and the devastation her death caused to relatives, coworkers, and patients in the cancer community she served. Prosecutors told the court that Angela had been shot 12 times and bore evidence of older injuries, arguing that these facts, combined with the absence of alcohol or drugs in her system, pointed away from an accident and toward a deliberate act of violence that would likely have been found premeditated had the case gone to trial.
Superior Court Judge Doug Camacho took into account Keven’s prior 2000 conviction in California for battery causing serious injury, the sheer number of shots fired, and the emotional trauma inflicted on Angela’s family. Concluding that the circumstances warranted the harshest punishment available under the plea deal, he sentenced Keven Scott Olejniczak to the maximum term of 25 years in prison for second-degree murder by domestic violence. Crime databases and case-tracking sites now list Angela’s homicide as solved, with her husband identified as the offender and serving a lengthy sentence.
In the years since her death, Angela’s memory has been kept alive through online memorials, candles lit in her honor, and heartfelt tributes from those who knew her best. Loved ones describe a woman who was “always bubbly,” willing to help anyone, a devoted mother and sister whose loss left an irreplaceable void. Images shared on her memorial pages show her smiling at family gatherings, working, and proudly wearing Broncos gear, reflecting a life full of warmth and community spirit cut short by domestic violence in her own home.
