On the afternoon of December 11, 2025, 38-year-old Kevin Karnes was shot and killed in the Tower Grove South neighborhood of Saint Louis, Missouri. Officers responded shortly after 3:00 p.m. to the 3700 block of Winnebago Street and found Karnes suffering from gunshot wounds; some reports say he was pronounced at the scene, others that he was taken to a hospital before dying.

Homicide detectives stated witness accounts placed Karnes in a verbal confrontation with a teenager just before shots were fired. Bystanders reported the young man was the only person observed with a firearm, and authorities later confirmed the two were related. A 19-year-old was arrested and charged with first-degree murder, unlawful use of a weapon, and two counts of armed criminal action. The Homicide Division is asking anyone with information to contact investigators or CrimeStoppers.
