ST. CLOUD, MN — A late-night 911 call from a St. Cloud apartment quickly escalated into a homicide investigation after 25-year-old Quinton McKay Hughes was found fatally stabbed during what authorities described as a volatile domestic dispute with his girlfriend of two months.
The woman accused in the killing, 23-year-old Katerina Ivanovna Markiv, now faces a second-degree murder charge as investigators piece together the chain of events that unfolded in the early morning hours.
911 Call Reveals a Disturbing Scene
According to a probable cause affidavit, the incident began around 4 a.m. Monday, when Hughes managed to call 911 and report that he had been stabbed following what he called a “minor disagreement.” Dispatchers noted that Hughes sounded distressed — coughing, gasping, and struggling to speak. Moments later, Markiv took over the call and described the wound as being “at his left f—ing nipple.”
She reportedly apologized repeatedly during the call, telling Hughes she did not mean to hurt him. But by the time officers arrived at the apartment on Washington Memorial Drive, they discovered Hughes unresponsive on the floor, surrounded by a significant amount of blood. Despite immediate medical intervention, the wound proved fatal.
Investigators recovered an 8-inch knife believed to have been used in the stabbing.
Suspect’s Statements Raise Questions
During her interview with authorities, Markiv gave a troubling account of the moments leading up to the stabbing. According to police, she described experiencing a sudden reaction:
“Something in my head got triggered to where my f—ing hand just went forward and it f—ing shanked him… it just happened. It literally was a reflex of mine.”
She allegedly insisted she did not want Hughes to die, telling officers she applied pressure to the wound and urged him to call 911. However, the surprising nature of her explanation — describing the stabbing as a reflexive action — quickly became a focal point of the investigation.
Authorities also noted inconsistencies between Markiv’s claims and the severity of the wound, as well as evidence at the scene.
Witness Accounts Paint a Troubling Picture
Two co-workers of the couple provided additional insight into the dynamic between Markiv and Hughes. One described Markiv as someone who would frequently become “upset and very unhappy,” while another reported a chilling comment she had made just a week earlier.

According to the affidavit, Markiv allegedly told a co-worker:
“She gets so crazy to the point she will kill somebody.”
Prosecutors say this statement could become a significant factor as the case proceeds, especially in establishing Markiv’s mindset and whether the stabbing could reasonably be considered unintentional, as she claimed.
Investigators have not reported any known history of violence between the pair during their brief relationship, though witnesses suggested Markiv exhibited increasingly unstable behavior.
Charges and Upcoming Court Proceedings
Markiv was arrested shortly after the incident and remains in custody at the Stearns County Jail. She is charged with second-degree murder, a felony that carries a potential decades-long prison sentence if convicted. Her next court appearance is scheduled for Monday, where prosecutors are expected to discuss bail, evidence, and the status of the investigation.
Authorities have not yet released additional details regarding the argument that preceded the stabbing or what may have triggered the sudden escalation of violence. Investigators say they continue to evaluate physical evidence, statements from both parties, and electronic communications to determine the timeline and motive.
Community Impact and Ongoing Concerns
The case has rattled the St. Cloud community, where domestic violence incidents — even those involving young couples with no known prior history — continue to raise alarm about the unpredictable nature of interpersonal conflicts. The sudden, violent loss of life has left Hughes’ family, friends, and co-workers searching for answers.
Legal experts note that Markiv’s own statements could be heavily scrutinized in court, especially her description of a “reflex” and previous comments about violent impulses. Prosecutors are expected to argue that the attack was intentional, not accidental, while defense attorneys may seek to challenge that interpretation.
Domestic violence cases often leave communities searching for ways to recognize warning signs before tragedy strikes. How do you think friends, co-workers, or neighbors can better identify early red flags and help prevent violent outcomes? Share your thoughts in the comments.
