Jason York

In the fall of 2023, the life of Jason York, a 37-year-old white male from Independence, Kansas, was brought to a violent end. On the morning of Monday, October 23, police were called to a home on West Cedar Avenue with reports of a shooting. Inside, they found York deceased. An investigation determined he had been shot multiple times.

The Kansas Bureau of Investigation and the Independence Police Department launched a homicide investigation that soon led them across state lines to Missouri. After several months of work, authorities secured arrest warrants for five individuals. The first arrests occurred on February 22, 2024, when the U.S. Marshals Service and the St. Louis County Sheriff’s Office apprehended three men in North St. Louis. The suspects were identified as 37-year-old Kevin A. Quinn, 20-year-old Aquan A. Quinn, and 23-year-old Kevin W. Martin, all residents of St. Louis.

The search for additional suspects continued. On March 14, a fugitive task force composed of U.S. Marshals and St. Louis County Police located and arrested two more men at a residence on Count Drive in St. Louis. Joshua B. Denton, 21, and Kayvion D. Williams, 18, were taken into custody. All five men were booked into the St. Louis County Jail on warrants for first-degree murder and aggravated robbery, pending extradition to Kansas to face the charges.

The Montgomery County Attorney’s Office prosecuted the five cases, which resulted in a series of convictions. Kevin A. Quinn was convicted by a jury and sentenced to life in prison for his role in the murder. Joshua B. Denton entered a plea agreement, pleading guilty in a Montgomery County courtroom to second-degree murder and two counts of aggravated robbery. Kevin W. Martin and Aquan A. Quinn also reached plea agreements and pleaded guilty in connection with the homicide. As of the latest reports, the case against Kayvion D. Williams was still pending.
