On the afternoon of January 14, 2025, Kansas City police responded to a disturbance on the 3900 block of North Lister Avenue and found 36-year-old Colton J. Stock outside a nearby home with a gunshot wound. He was taken to a hospital and pronounced dead shortly after arrival. Officers also found another adult male inside the residence with gunshot injuries; that man was transported to a hospital in critical but stable condition.

Detectives reported the violence began as an argument between the two men and escalated into an exchange of gunfire, with both appearing to shoot at each other. Police said they were not actively seeking additional suspects and saw no immediate indication the fatal shooting was connected to Stock’s earlier legal history. Years earlier Stock had been tried in the 2019 death of Matthew Calkins; a Clay County jury acquitted him of first-degree murder and armed criminal action in December 2022 but convicted him of abandoning a corpse and tampering with physical evidence. Stock had been released from custody in September 2024.

Does anyone have information about the Lister Avenue dispute or knew the relationship between the two men involved?
