Greenville, MS— Jamirrus Doby, 23, of Greenville was sentenced to thirty years following his guilty plea earlier in this term of court, District Attorney Dewayne Richardson announced today.

On the night of April 5, 2019, officers with the Greenville Police Department were called to Lewis Street where they located the deceased body of Riko Robinson lying halfway out of a wrecked vehicle with gunshot wounds to his side and back. Shell casings were located in the vehicle and on the ground outside of the vehicle.

Detectives with the Criminal Investigations Division arrived on scene to initiate their investigation. They confirmed that the vehicle was registered to a relative of Jamirrus Doby and that Doby and his associate Demanuel Flowers had borrowed the car earlier that day and never returned it. Flowers was tracked down at a hospital in Arkansas where he checked himself in for a gunshot wound and Doby was arrested later. Flowers and Doby initially claimed self-defense, but when confronted with the physical evidence that contradicted their accounts, both defendants began to provide conflicting versions of events that did not account for Robinson being shot from behind and the path of the bullet that struck Flowers, which the evidence showed was fired by Doby.

Demanuel Flowers previously pled guilty to Manslaughter in October of 2022 and was sentenced to twenty (20) years in the custody of the Mississippi Department of Corrections for his role in Riko Robinson’s death. Doby recently pled guilty in January to Manslaughter and Possession of a Firearm by a Convicted Felon. He was sentenced to the District Attorney’s recommendation of thirty (30) years in MDOC custody.

This case was prosecuted by Assistant District Attorneys Kaylon McCou and Austin Frye who expressed their thanks to the Greenville Police Department’s Criminal Investigation Division for their efforts and to the family of Riko Robinson for their patience as our office worked to bring them some sense of justice and closure.
