HERMANN, MO – The quiet of a small Missouri town was shattered nearly three years ago when a gunman opened fire inside a convenience store, ending the life of a local police sergeant and forever altering the fate of another officer. This weekend, after hours of deliberation, a jury reached a verdict: Kenneth Simpson, 38, was found guilty of first-degree murder and first-degree assault, a decision that brings the possibility of the death penalty as his sentence.
The events unfolded on the evening of March 12, 2023, at a typically unremarkable Casey’s convenience store in Hermann, a town better known for its vineyards than violent crime. On that night, however, the store turned into a crime scene following reports of a disruptive individual causing alarm among employees and customers alike.
Authorities responded swiftly. Sergeant Mason Griffith, 34, and Detective Adam Sullentrup, also 34, arrived to investigate and quell the disturbance. Both men were part of the Hermann Police Department, well-acquainted with the rhythms of their town and the people who lived there. Yet nothing could prepare them for what was about to unfold.
Simpson, who had outstanding warrants in multiple counties, did not intend to go quietly. Witness testimony revealed he was agitated, behaving unpredictably, and gave indications he was preparing for a confrontation. One witness recounted feeling an uneasy tension in the air, describing Simpson’s demeanor as menacing.
Surveillance footage shown to the jury later captured the officers approaching Simpson, speaking calmly without their weapons drawn. Moments later, in a flash of violence that sent shockwaves through Hermann, Simpson drew a gun and fired multiple shots, striking both officers in the store’s aisles.
As the chaos erupted, some bystanders risked their own safety in desperate attempts to save the wounded. Employees and customers rushed to the fallen men, administering aid as best they could and placing urgent calls for help. Detective Sullentrup survived his injuries following hospitalization, but Sergeant Griffith died at the scene, leaving colleagues and loved ones to grapple with the loss.
The days that followed saw a tense manhunt across the region’s rolling hills. Simpson was located and apprehended after a high-stakes standoff with state police the next day, bringing a close to the search but setting the stage for a lengthy and emotionally charged trial.
Testimony from witnesses at the store painted a chilling picture of the confrontation. Some recalled prior encounters with Simpson, suggesting his presence immediately raised red flags. One employee recounted recognizing him and described an atmosphere thick with suspicion and fear long before the shooting started.
During the trial, jurors heard harrowing details and reviewed critical evidence, including video footage and eyewitness accounts. The jury ultimately convicted Simpson on the most serious charges, holding him accountable for killing Sergeant Griffith and injuring Detective Sullentrup.
Now, with sentencing yet to be determined, Simpson faces the stark consequences of his actions: either life behind bars without parole or, potentially, a death sentence. The verdict has brought a measure of closure for the town of Hermann, but the pain of that deadly night lingers for the officers’ families, their colleagues, and the community they served.
