Beyond “Serious Injury”: Missouri Courts Redefine When Deadly Force is Justified

Published February 26, 2026

The Missouri Supreme Court has declined to hear a challenge to a landmark appellate ruling, effectively expanding the legal grounds for using deadly force in self-defense. The decision upholds a lower court’s finding that Missouri law allows for deadly force to prevent a “forcible felony,” even in instances where there is no immediate risk of death or serious physical injury.

JEFFERSON CITY, MO — Something big has changed in Missouri when it comes to defending yourself. On Tuesday February 24 2026 the Missouri Supreme Court said it would not hear an appeal in the case of Danielle Lechocki. This means a ruling from November is now the law of the state. The Missouri Association of Prosecuting Attorneys is really upset about this decision. They think it means people can turn fights into big ones with guns and say they were defending themselves.

This all started in 2022 when Danielle Lechocki, a Marine got into a fight at a homeless shelter for veterans. Another woman threatened to hurt her so Lechocki pulled out a knife. The judge at her trial would not let her say she was defending herself so she was found guilty.. Then the Eastern District Court of Appeals said the judge was wrong. They said changes to Missouris laws about using force in 2007 meant people have more right to defend themselves than they used to.

Forcible Felonies vs. Serious Physical Injury

The main issue here is what Missouris “Stand Your Ground” law and self-defense laws really mean. Judge Gary M. Gaertner Jr. Said the law lets people use force to protect themselves from someone who is committing a serious crime even if that person is not trying to kill them right then. Prosecutors are worried this means people can use force even when someone is just pushing them.. The court said people still have to be reasonable and use the right amount of force.

This ruling is a deal for people in Missouri who own guns. It means a jury, not a judge gets to decide if someone was really scared and had a reason to defend themselves. Danielle Lechockis lawyer, Christian Lehmberg said this decision is fair because it lets law-abiding citizens explain why they did what they did in court. The Missouri Supreme Court decision in the case of Danielle Lechocki is very important, for Missouris self-defense laws.

Safety Tip: While this ruling expands the legal “gray area” in your favor, the tactical reality remains: the best fight is the one you avoid. Always prioritize de-escalation and escape.
