A Las Vegas woman rejected a plea deal that would have made her eligible for parole in 15 years, only to face trial and receive a sentence of 28 years to life for brutally killing and beheading her ex-boyfriend.
Story Snapshot

- The victim was the father of her two daughters and also the father of her current husband, creating a twisted family triangle
- Michaels admitted to killing Ouellette during police interrogation but denied cutting off his head
- She rejected a second-degree murder plea that offered parole eligibility after 15 years, leading to a harsher sentence
- Sentenced to 28 years to life in January 2026 after jury conviction
The Fatal Decision That Changed Everything
Devyn Michaels faced a crossroads that would determine whether she spent 15 years or potentially the rest of her life behind bars. Prosecutors offered her a second-degree murder plea deal with parole eligibility after 15 years. She walked away from that deal, proclaimed her innocence on key aspects of the crime, and rolled the dice with a jury trial.
The gamble backfired spectacularly. In November 2025, a Clark County jury convicted her of first-degree murder for the August 2023 killing of Jonathan Ouellette. The judge sentenced her to 28 years to life in January 2026, nearly doubling her minimum time behind bars compared to the rejected plea deal.
A Family Triangle That Turned Deadly
The circumstances surrounding this case read like a disturbed soap opera script. Michaels had two daughters with Ouellette during their previous relationship. After they separated, she married his adult son, Deviere. By summer 2023, Ouellette planned to move back into the home where Michaels lived with his son.
Prosecutors argued this arrangement triggered the deadly confrontation. They contended Michaels feared Ouellette’s return would disrupt her life with Deviere and destabilize their household. The defense flipped this narrative, suggesting Deviere himself might have killed his father to prevent a potential reconciliation between his wife and his father.
The Brutal Crime and Damning Confession
On August 7, 2023, in a Las Vegas-area garage workshop, Michaels attacked Ouellette with what prosecutors described as a three-foot metal pipe. She bludgeoned him, causing massive head trauma, then decapitated him after he was dead or incapacitated. She poured chemicals on the body and attempted to dispose of his remains, including discarding his head.
During police interrogation, Michaels made statements that would seal her fate at trial. She admitted killing Ouellette, telling detectives “he was pissing me off, so I killed him.” However, she steadfastly denied being capable of cutting off his head, a denial she maintained even at sentencing while facing the possibility of appeal.
Justice Served, But Questions Remain
The conviction represents a clear victory for prosecutors who successfully argued Michaels alone committed this heinous crime. The forensic evidence, combined with her partial confession, convinced jurors to reject the defense theory pointing toward her husband. Yet Michaels continues to deny responsibility for the beheading specifically, setting up potential grounds for appeal.
This case exemplifies the consequences of rejecting reasonable plea agreements in favor of rolling the dice at trial. Michaels gambled that she could convince a jury she wasn’t fully responsible for the most gruesome aspects of the crime. Instead, she now faces the possibility of spending most or all of her remaining life in prison, while her two daughters have lost both their father to violence and their mother to the justice system.
