The Apple River Stabbing: Self-Defense, Minors, and the Weight of Public Scrutiny

UPDATE ARTICLE by Jeffrey Straub Sponsored by 2A Self-Defense Law The Apple River Stabbing: Self-Defense, Minors, and the Weight of Public Scrutiny The Nicolae Miu Case (Wisconsin, 2022 to 2025) In July 2022, what started as a typical summer tubing trip down the Apple River—a well-known spot in western Wisconsin—turned into one of the most closely watched self-defense cases in the region. Nicolae Miu, a 54-year-old mechanical engineer and Minnesota resident, was tubing with his wife and friends. At some point, Miu became separated from his group and approached a separate group of teenagers. According to Miu, he was searching for a lost phone and trying to reconnect with his party. The teens accused him of being a “creep,” and a confrontation followed. Most of the group was intoxicated. Video footage and testimony confirmed that things escalated quickly. Miu ended up stabbing five individuals, killing 17-year-old Isaac Schuman and injuring four others. But video evidence also revealed something damning: Miu may have displayed his knife before any physical contact occurred, and some of the individuals stabbed were not actively attacking him. On top of that, witness testimony confirmed that Miu walked away from the group initially but then re-approached—re-entering a volatile situation he had the opportunity to avoid. That decision—to circle back into a hostile, drunken crowd—undercut his self-defense claim in court. Self-Defense or Recklessness? Miu’s legal team argued that he was surrounded, shoved, and in fear for his life. From a pure self-defense standpoint, he checked several boxes: multiple aggressors, disparity of numbers, and an escalation that became physical. But Wisconsin law, like most states, doesn’t stop at checking boxes. The jury also looked at: 1. Proportionality – The teens were unarmed. Miu’s use of a deadly weapon—a knife—was viewed as excessive, particularly because he stabbed more than one person and not all of them were physically threatening him at the time. 2. Avoidance – Wisconsin is not a strict duty-to-retreat state, but the law still looks at whether the defendant made reasonable efforts to avoid conflict. In this case, Miu had left and then came back. That fact was devastating to his claim. 3. Credibility and Mens Rea – After the stabbing, Miu left the scene, disposed of the knife, and lied to police. These actions signaled to the jury that Miu knew what he did was wrong. That’s where “consciousness of guilt” comes in. The jury didn’t need to decide whether he was scared—they needed to decide whether a reasonable person in his situation would have re-entered that fight, brandished a deadly weapon, and used it as he did. They decided no. Sidebar: Brandishing in Wisconsin vs. Other States Some have asked: what if Miu only intended to scare the teens off by showing his knife? Here’s the problem: Wisconsin, like Minnesota, does not have a separate “defensive display” statute that protects someone who merely shows a weapon to deter violence. In states like Arizona, threatening to use force (without actually using it) can be a lawful form of self-defense. Wisconsin doesn’t offer that shield. If you’re going to display a weapon, it has to meet the same legal requirements as actually using it—including necessity, proportionality, and reasonableness. And here’s the real-world issue: the teenagers were drunk. If Miu was hoping to scare them off, it didn’t work. They didn’t back down. So when he drew the knife and they didn’t retreat, he escalated. It went from bluff to blood in a matter of seconds. The Loss of Innocence Another underappreciated aspect of this case is the loss of the “innocence” standard. To claim self-defense under Wisconsin law, you cannot be the initial aggressor or someone who re-engages a conflict unnecessarily. When Miu left the group and then returned, that move destroyed any claim that he was merely defending himself from a spontaneous threat. He went back into a confrontation that he could have left behind. That action flipped the perception. Instead of being an older man backed into a corner, Miu became a man who inserted himself back into a fight with minors—and then used a deadly weapon when it spiraled. The Verdict and Sentencing Miu was charged with first-degree intentional homicide and multiple counts of attempted homicide. But the jury found him guilty of lesser—but still serious—charges: • First-degree reckless homicide (Isaac Schuman’s death) • Four counts of first-degree recklessly endangering safety • One count of battery In July 2024, he was sentenced to 20 years in prison and six years of extended supervision. He was credited for time served—732 days. During sentencing, the judge acknowledged his lack of criminal history but called out his poor judgment and failure to de-escalate. The Civil Lawsuit (2025) In March 2025, four surviving victims—Ryhley Mattison, Alexander “AJ” Martin, Dante Carlson and Anthony “Tony” Carlson—filed a civil lawsuit against Miu and his insurance company. The lawsuit seeks damages for: • Physical injuries • Psychological trauma • Conscious pain and suffering Because the standard in civil court is lower (“preponderance of the evidence” instead of “beyond a reasonable doubt”), Miu could be found liable even though he’s already serving a criminal sentence. A jury trial has been requested. Community Impact Apple River was once a casual summer retreat for families and college kids alike. After the incident, it became synonymous with violence and tragedy. Local business owners reported a drop in tourism, and the case became a cautionary tale: how fast a day in the sun can turn deadly. Key Takeaways for the Self-Defense Community 1. Innocence matters. If you leave a conflict and then come back into it, you may lose your legal claim to self-defense—regardless of what happens next. 2. Brandishing is not a get-out-of-jail-free card. Wisconsin does not protect “defensive display” as a separate act. If you show your weapon, it better meet all the same legal thresholds as using it. 3. Drunk aggressors don’t always act rationally. Trying to bluff with a weapon may backfire—especially if the threat isn’t taken seriously. 4. Proportionality matters. Using a knife on a group of unarmed minors—even if they’re hostile—will rarely go over well with a jury. 5. Post-incident behavior will be used against you. Running, hiding the weapon, and lying to law enforcement scream “I knew I was wrong.” 6. Mens rea is inferred from conduct. Your mindset doesn’t just come from your words; it’s revealed by your actions after the fact. 7. Self-defense doesn’t shield you from civil lawsuits. Criminal and civil law are separate. Even if the criminal charge had failed (which it didn’t), the civil case would still be live. 8. Juries are human. A middle-aged man stabbing teenagers is a tough visual. It doesn’t take much to turn legal facts into emotional convictions. 9. Understand your state’s law. Miu’s case happened in Wisconsin. Had it happened in Arizona or Texas, the jury instructions and use-of-force standards might have been different. You must know the law where you are, not where you wish you were. ⸻ About the Author Jeffrey Straub is the founder of 2A Self-Defense Law and a longtime advocate for concealed carry education and self-defense literacy.
