Incident Summary Update
The Apple River stabbing stands as one of the most highly publicized and emotionally charged midwestern legal trials in recent years. The incident occurred on July 30, 2022, during a popular summer tubing weekend on the Apple River in the Town of Somerset, Wisconsin. What began as a routine recreational outing quickly deteriorated into a fatal, multi-person confrontation that left one teenager dead, four other tubers severely wounded, and a community deeply fractured.
The legal proceedings culminated in the high-profile trial of Minnesota resident Nicolae Miu, who was ultimately convicted and sentenced to significant prison time after a jury rejected his comprehensive claims of self-defense.
The Confrontation: Lost Phones and Escalation
On the afternoon of the incident, Nicolae Miu (then 54) separated from his immediate tubing party to search the riverbed near the Sunrise Bridge for a friend’s lost cell phone, equipped with a snorkel and goggles. While wading through the water, he encountered a group of young tubers.
The interaction rapidly turned volatile. Members of the tubing group accused Miu of behaving inappropriately and approaching minors in the water, an accusation his defense strongly denied as groundless. As a larger group of tubers converged on the scene, insults were exchanged, and multiple individuals began surrounding and taunting Miu. Extensive cell phone video captured by a bystander showed Miu being pushed into the water before he stood back up, brandishing a folding pocket knife.
Within minutes, the physical altercation erupted into a mass casualty event:
-
Isaac Schuman, a 17-year-old high school student from Stillwater, Minnesota, sustained a fatal stab wound to the chest and died shortly after impact.
-
Four other individuals—Ryhley Mattison, Alexander Martin, Dante Carlson, and Anthony Carlson—suffered severe upper-body and abdominal stab wounds that required emergency trauma interventions.
-
Miu fled the immediate scene downriver, where he was subsequently detained by St. Croix County sheriff’s deputies later that evening.
Trial Breakdown and Active Legal Claims
The criminal trial, State of Wisconsin v. Nicolae Miu, commenced in April 2024 at the St. Croix County District Court in Hudson, Wisconsin. Over an intense eight-day period, prosecutors and defense teams presented vastly contrasting narratives to the jury.
The state’s prosecution team focused heavily on the bystander cell phone videos, arguing that Miu acted out of anger, isolation, and public humiliation rather than fear. They emphasized that Miu had numerous clear opportunities to de-escalate the situation, turn around, or float away from the confrontational teenagers before pulling out his weapon.
Conversely, Miu’s defense counsel argued that he was the victim of a coordinated assault by an “angry mob” of intoxicated tubers. They asserted that Miu reasonably feared for his life when he was surrounded on three sides and physically knocked down into the riverbed, justifying the use of lethal force in self-defense.
Legal Charge Filed vs. Final Jury Conviction Profile
----------------------------------------------------------------------------------
Original State Charge Final Jury Verdict (April 11, 2024)
----------------------------------------------------------------------------------
1st-Degree Intentional Homicide GUILTY: 1st-Degree Reckless Homicide (Schuman)
4 Counts: Attempted Homicide GUILTY: 4 Counts: Recklessly Endangering Safety
1 Count: Substantial Battery GUILTY: 1 Count: Battery (Madison Coen)
After roughly seven hours of deliberation, the jury returned a unanimous guilty verdict across all counts. While they opted not to convict Miu on the top-tier “intentional” homicide charges, they firmly found him criminally liable under lesser-included “reckless” behavior statutes, determining that his deployment of the knife constituted an unjustifiable disregard for human life.
Final Court Sentencing and Current Status
On July 31, 2024, exactly two years and one day after the fatal encounter, St. Croix Circuit Court Judge Michael Waterman handed down the final sentencing ruling. The prosecution team had requested a consecutive sentence totaling 70 years behind bars to ensure long-term public safety.
Judge Waterman ultimately sentenced Nicolae Miu to 20 years in state prison, followed by 6 years of extended post-release supervision. The judge ordered the prison sentences for each of the six counts to run concurrently (simultaneously), while granting Miu credit for the 732 days he had already spent in county jail awaiting trial.
During his address to the court, Miu wept and expressed deep remorse, stating his soul was broken over the tragic loss of young life. In delivering the sentence, the court noted that while Miu was unlikely to re-offend, a significant prison sentence was necessary because he fundamentally broke the social compact by introducing a deadly weapon into a verbal dispute. Miu remains incarcerated in the Wisconsin state correctional facility system serving out his term.
