Tarcari Tyshun Walker, 24, was shot and killed in Columbus, Mississippi, on November 9, 2020, near Seventh Avenue North and 22nd Street around noon. Walker, who was on foot, approached a red or maroon Jeep driven by a man he appeared to know; an argument followed and a single gunshot struck Walker in the chest. He ran to the porch of a nearby home, collapsed there, and was later pronounced dead after officers and first responders attempted CPR. His body was taken to the state Medical Examiner’s Office in Pearl for autopsy.

The Columbus Police named 21-year-old Jatavis Deonte Williams as a person of interest; Williams turned himself in two days after the shooting and was charged with murder. A grand jury in the 14th Circuit Court District returned an indictment in November 2021. In an August 2022 trial the prosecution said Williams intentionally shot Walker, while the defense argued self-defense, claiming Walker had been acting erratically and Williams feared for his life. The jury convicted Williams of first-degree murder and he received a life sentence.

Did anyone in Columbus know Walker or witness the argument that led up to the shooting?
