MOUNT VERNON, Ill. — A man has received a 75-year prison sentence after being found guilty of murdering his wife, whose body was discovered in their vehicle following a police stop in southern Illinois. John W. Finney, 52, was convicted of first-degree murder in connection with the death of 42-year-old Amy J. Finney, marking a significant conclusion to a case that began with a homicide report on September 1, 2025.
The tragic events unfolded on the evening of September 1, when the Jefferson County Sheriff’s Office received a tip regarding a possible homicide originating from the couple’s home. Officers were alerted to a gray 2007 Ford Escape suspected to be linked to the case. Within an hour, police located the vehicle traveling along Illinois Highway 14, leading to a traffic stop on Birch Road in rural Du Quoin, where John Finney was detained.
During a preliminary search of the Ford Escape, officers discovered Amy Finney’s lifeless body in the hatchback area of the vehicle. While law enforcement examined the scene, additional deputies were dispatched to the couple’s residence on North Illinois Highway 148. Their investigation confirmed that the home served as the location of the crime, revealing evidence that Amy Finney had died from a gunshot wound inflicted during a domestic dispute with her husband. Although details surrounding the incident have not been fully disclosed, initial findings suggested the shooting occurred a day prior.
The multi-county investigation garnered significant attention, with various law enforcement agencies involved, including the Jefferson County Sheriff’s Office and the Illinois State Police. Crime scene technicians meticulously processed both the residence and vehicle, collecting multiple pieces of evidence, though specifics have not been publicly revealed. Reports indicated John Finney’s cellphone GPS tracked his movements for several hours across the county prior to his arrest.
John Finney was arrested shortly after the traffic stop and subsequently booked into the Jefferson County Jail. By the time of his sentencing in June 2026, he had turned 52. The jury’s verdict confirmed that prosecutors successfully established their case against him. Following the sentencing, Finney was transferred to the Illinois Department of Corrections to begin serving his lengthy sentence, which will be governed by state prison regulations.
Authorities noted that the case transitioned rapidly from a homicide report to an arrest in just one hour. The sequence of events highlighted the effective collaboration among the various police departments responding to the crime. The search of the vehicle and home ultimately solidified the evidence against John Finney, underscoring the tragic circumstances surrounding Amy Finney’s death.
Although the investigation is now concluded, questions remain regarding the domestic dynamics of the Finneys, as well as the specific circumstances leading to the initial 911 call. The case serves as a poignant reminder of the serious nature of domestic disputes and the far-reaching implications they can have on families and communities. While John Finney awaits transfer to state prison, the impact of their tumultuous relationship will resonate with both the local community and those who followed the unfolding events.
