Mario Walker, 29, was killed after an assault on the evening of Tuesday, July 26, 2022, in Plaquemine, Louisiana. Walker was walking at the intersection of W.W. Harleaux and Calvin streets around 5:45 p.m. when a black Mercedes blocked his path and three men got out. Walker rose and tried to flee, and a second man, 30-year-old Jaymetrice Provo, allegedly fired a single fatal shot into the back of Walker’s head. Walker was airlifted to a hospital and died the next day, July 27, 2022.

The three occupants of the Mercedes fled Louisiana but were stopped later that night in Alabama after an Alabama State Trooper noticed the vehicle had no license plate. All three were arrested and returned to Plaquemine. Charges listed upon their return include second-degree murder and possession of a firearm by a convicted felon against Jaymetrice Provo, principals to second-degree murder and firearm possession charges against Jontrell Wilson, and accessory after the fact to second-degree murder for Jaylon Smith.

Did anyone in Plaquemine see the black Mercedes or the men that evening who can add details to the timeline?
