Sean Waldon

Sean Waldon, 32, was murdered on Friday after an argument with another man over whose car was the fastest. St. Louis County prosecutors on Saturday charged Deonte M. Robinson, 23, with first-degree murder and armed criminal action. Police said Robinson had been arguing with Waldon at a home near the 9400 block of Miriam Avenue in Overland when the fight turned physical. Waldon tried to get into a car to leave with his family when Robinson shot him, police wrote in court documents.
