On the late morning of September 10, 2015, James Jim Christopher Knowlton, 42, was found unconscious in the driver’s seat of his parked car on the 300 block of Central Avenue South in Kent, Washington. Bystanders began CPR and called 911; medics later pronounced him dead at the scene. A single gunshot wound to his upper torso was discovered, and investigators classified the case as a homicide.

Detectives developed leads that pointed to the East Hill area of Kent and took a 37-year-old acquaintance into custody. The suspect told police he confronted Knowlton as Knowlton was preparing to drive away because he felt Knowlton had been disrespecting his mother. The suspect said the gun discharged as he pointed it at Knowlton; witnesses were reportedly told to call for help before some people left the scene and the suspect was arrested and booked on a charge of second-degree murder.

Did anyone in the Kent area know Knowlton, the acquaintance, or witness the confrontation on Central Avenue South that morning?
